How to sustain a social media presence in 3 hours a week

18 Mar

When it rains on a weekend, I don’t bemoan my decision to live in the Pacific Northwest: I just know it’s time to queue up my blog posts and tweets for the week. That’s what I try to do in about two hours every weekend, and since folks often ask me how they can keep their social media presence alive in an efficient and sustainable way, I figure I’m long overdue to blog my system.

First, let me come clean. I don’t maintain my social media presence in just 3 hours a week; for me, it’s more like 40. But that is because social media is what I do, and I do a lot of it: I write for five different sites, contribute to seven different Twitter feeds, and aim to write at least 3 (typically 4 or 5) in-depth posts per week. All that social mediafying is the heart of my work, and more importantly, I love it. I would write that much even if it weren’t my work, so I’m just incredibly lucky that it is.

For most people, however, 40 hours a week would be overkill. And the same approach I use to maintain all my different social media activities can support a much more streamlined — but still very effective — presence. Three hours a week is enough to:

  1. Tweet original content 2-3x day, 5 days/week
  2. Publish 3 blog posts per week
  3. Reply to comments on your blog posts
  4. Reply, retweet and engage in conversation on Twitter

Let’s start with items #1 and #2 — which is what I spend about two hours tackling each weekend. If you’ve got your setup in place, that two hours is all you need to keep your social media presence alive and useful. By “useful”, I mean useful to the people you are trying to reach…which in turn makes it useful to you. The point isn’t to queue up a bunch of junk that keeps your blog and Twitter presence notionally alive: the point is to spend two hours teeing up some content that will provide real value to your target audience by speaking to the topic on which you are (or wish to be) an expert.

Here’s how:

  1. Open up Google Reader and look at the latest blog posts and news stories that are coming in through the custom searches you’ve set up and subscribed to. I’ve put my searches into a separate folder so it’s easy for me to see all latest results in one place:
  2. IRL searches viewed in Feedly

    Does my Google Reader look prettier than your Google reader? That's because I view my Google Reader feeds in Feedly.

    Quickly scan through the teasers for all the stories that look interesting, Command-clicking (that’s ctrl-clicking for you Windows users) on anything that looks interesting so it opens in a new tab. I do that until I have ten or fifteen tabs open:

    Many tabs open in Chrome

  3. Flip through the tabs and skim (or where warranted, read) each post or story in turn. It’s a sudden death system: as soon as I read something that makes me think that what I’m reading is too stale, too weird, too off-topic or too poorly written to share or respond to, I stop reading and close the tab.
  4. If you find something useful, queue it up as a tweet in HootSuite. If you’ve got the “hoot this” bookmarklet installed, it will likely pre-populate your tweet with the title of what you’re sharing:
  5. Hootsuite bookmarklet prepopulated with story title

    At this point your fastest option is to just hit the calendar icon and pick a date and time when you want your tweet to go out, but I like to customize at least half of my scheduled tweets so that they reflect my voice and are more intriguing:

    Hootsuite bookmarklet with tweet rewritten as "Disable chat (please!!!) plus 4 more tips on how to use Facebook without letting it take over your life!"

  6. Continue flipping through your tabs, skimming and tweeting, but watch out for scrapers. A lot of content you find online will be scraped (i.e.republished or stolen) from other sites. I can’t give you a hard-and-fast rule for spotting scraped content, but you’ll get a feel for it. For example, this page on Youth Service America just didn’t look like it matched the voice of a blog post about online dating. I selected a string of text, dropped it into Google search, and sure enough, it turned up as a blog post that originally appeared on the Social Citizens blog. (It looks like YSA republishes the Social Citizens blog in a totally legit way, but I’d like to share the original post, not the reprint.)
  7. Look for the most thought-provoking stories and posts. When you hit something that’s especially interesting, insightful or simply annoying — something that makes you want to share your own perspective — then don’t tweet it. Instead, use it as the jumping-off point for a short blog post. Your post can share an excerpt or two from the source of your inspiration, but should do more than link to the post. You need to add your own perspective on it, or simply share the questions it raises for you. A blog post like this, which might be 2-4 paragraphs long, can take 5-15 minutes to write. That means you can queue up 3 blog posts in under an hour. (Don’t believe me? My next post in this series will offer proof.)
  8. Schedule your blog posts to go out on 3 different days of the week by setting the publication date and time in WordPress:
    Publish immediately with "edit" link you can click to schedule Date and time fields to edit publication time in WordPress
    Click “edit” next to “Publish immediately”…. …and you can choose when to post.

    That might be Monday, Wednesday and Friday, or perhaps Monday, Tuesday, Thursday; I often front-load my prewritten blog posts because I usually get inspired to write something here or there over the course of the week. I drop those longer, original posts into my schedule on the days I don’t have a post lined up, or I adjust my schedule to make room for them. I usually schedule my posts to go live between 9-10 am, when people in my time zone (Pacific) are at work and people on the east coast are ready for something to read over lunch.

  9. Queue up tweets about each of your blog posts on the day it’s scheduled to be published. Make sure you don’t link to the “preview post” URL you get while editing (where it says “post draft updated” when you save a draft) — that’s not the URL that will let people access your blog post once it’s published. Once you’ve got your post written and scheduled, WordPress will give you a new “preview post” link with the real URL for your post. You’ll know you’ve go the real URL if it doesn’t include the word “preview” in the address.

    Link to "preview post" next to "Post Scheduled"

    This links to the actual URL of your soon-to-be-published post.

  10. Review your “pending tweets” column in HootSuite (you may have to add it if it’s not already part of one of your HootSuite tabs) to see if your tweets are scheduled out evenly. You can click on any pending tweet to edit its text or scheduled time. Ideally you’ll have two or three tweets about other people’s content scheduled each day, and you will have the tweets about your own blog posts spaced out with tweets about other people’s content so that you’re never tweeting your own stuff twice in a row.

And that’s it! Well, almost. Remember items #3 and #4 at the top of this page — where I point out that you need to reply to your blog comments, Twitter mentions, and just generally participate in the Twitter conversation? That’s what your third social media hour is for.

I’m confident that you can queue up 3 blog posts and 10-15 tweets in just two hours each weekend. But that investment won’t do much for you unless you spend that additional hour — ideally as 10 or 15 minutes, 4-5 days a week — engaging with your community.

And yes, you will have a community. Because once you commit two hours a week to delivering real value to the audience you care about, you’re going to have people reading, tweeting and talking to you. So please, don’t forget to talk back.

An Airport Encounter

18 Mar

It was only the third time it had happened to me in my nearly thirty-five happy years as a priest, all three times over the last nine-and-a-half years.

Other priests tell me it has happened to them a lot more.

Three is enough.  Each time has left me so shaken I was near nausea.

It happened last Friday . . .

I had just arrived at the Denver Airport, there to speak at their popular annual “Living Our Catholic Faith” conference.

As I was waiting with the others for the electronic train to take me to the terminal, a man, maybe in his mid-forties, waiting as well, came closer to me.

“Are you a Catholic priest?” he kindly asked.

“Sure am.  Nice to meet you,” says I, as I offered my hand.

He ignored it.  “I was raised a Catholic,” he replied, almost always a hint of a cut to come, but I was not prepared for the razor sharpness of the stiletto, as he went on, “and now, as a father of two boys, I can’t look at you or any other priest without thinking of a sexual abuser.”

What to respond?  Yell at him?  Cuss him out?  Apologize?  Deck him?  Express understanding?  I must admit all such reactions came to mind as I staggered with shame and anger from the damage of the wound he had inflicted with those stinging words.

“Well,” I recovered enough to remark, “I’m sure sorry you feel that way.  But, let me ask you, do you automatically presume a sexual abuser when you see a Rabbi or Protestant minister?”

“Not at all,” he came back through gritted teeth as we both boarded the train.

“How about when you see a coach, or a boy scout leader, or a foster parent, or a counsellor, or physician?”  I continued.

“Of course not!” he came back.  “What’s all that got to do with it?”

“A lot,” I stayed with him, “because each of those professions have as high a percentage of sexual abuse, if not even higher, than that of priests.”

“Well, that may be,” he retorted.  “But the Church is the only group that knew it was going on, did nothing about it, and kept transferring the perverts around.”

“You obviously never heard the stats on public school teachers,” I observed.  “In my home town of New York City alone, experts say the rate of sexual abuse among public school teachers is ten times higher than that of priests, and these abusers just get transferred around.”  (Had I known at that time the news in in last Sunday’s New York Times about the high rate of abuse of the most helpless in state supervised homes, with reported abusers simply transferred to another home, I would have mentioned that, too.)

To that he said nothing, so I went in for a further charge.

“Pardon me for being so blunt, but you sure were with me, so, let me ask:  when you look at yourself in a mirror, do you see a sex abuser?”

Now he was as taken aback as I had been two-minutes before.  “What the hell are you talking about?”

“Sadly,” I answered, “studies tell us that most children sexually abused are victims of their own fathers or other family members.”

Enough of the debate, I concluded, as I saw him dazed.  So I tried to calm it down.

“So, I tell you what:  when I look at you, I won’t see a sex abuser, and I would appreciate the same consideration from you.”

The train had arrived at baggage claim, and we both exited together.

“Well then, why do we only hear this garbage about you priests,” he inquired, as he got a bit more pensive.

“We priests wonder the same thing.  I’ve got a few reasons if you’re interested.”

He nodded his head as we slowly walked to the carousel.

“For one,” I continued, “we priests deserve the more intense scrutiny, because people trust us more as we dare claim to represent God, so, when on of us do it – even if only a tiny minority of us ever have — it is more disgusting.”

“Two, I’m afraid there are many out there who have no love for the Church, and are itching to ruin us.  This is the issue they love to endlessly scourge us with.”

“And, three, I hate to say it,” as I wrapped it up, “there’s a lot of money to be made in suing the Catholic Church, while it’s hardly worth suing any of the other groups I mentioned before.”

We both by then had our luggage, and headed for the door.  He then put his hand out, the hand he had not extended five minutes earlier when I had put mine out to him.  We shook.

“Thanks.  Glad I met you.”

He halted a minute.  “You know, I think of the great priests I knew when I was a kid.  And now, because I work in IT at Regis University, I know some devoted Jesuits.  Shouldn’t judge all you guys because of the horrible sins of a few.”

“Thanks!,” I smiled.

I guess things were patched-up, because, as he walked away, he added, “At least I owe you a joke:  What happens when you can’t pay your exorcist?”

“Got me,” I answered.

“You get ‘re-possessed’!”

We both laughed and separated.

Notwithstanding the happy ending, I was still trembling . . . and almost felt like I needed an exorcism to expel my shattered soul, as I had to confront again the horror this whole mess has been to victims and their families, our Catholic people like the man I had just met . . . and to us priests.

Spacecraft Swings Into First Orbit Around Mercury

18 Mar

NASA’s Messenger spacecraft swung into position around Mercury Thursday night, making it the first spacecraft ever to orbit the innermost planet.

Engineers at the Johns Hopkins University Applied Physics Laboratory in Maryland, 96 million miles from Mercury, received the signal confirming that Messenger (MErcury Surface, Space ENvironment, GEochemistry and Ranging) had completed its final maneuver at 9:10 pm EDT.

To slow down enough to get caught in Mercury’s gravitational field, Messenger fired its main thruster for 15 minutes. The burn slowed the spacecraft by 1,929 mph and used up 31 percent of its original fuel supply.

After finishing the burn, Messenger rotated to face the Earth by 9:45 p.m., and started transmitting data. Engineering and operations teams confirmed the maneuver went according to plan.

The event marks the end of a 6½-year journey for Messenger, which has made 12 laps around the solar system, two flybys past Earth, one past Venus and three past Mercury since launching in August 2004.

Although engineers still need to do some analysis to figure out the spacecraft’s exact orbit, they expect Messenger to swoop around Mercury in a highly elliptical orbit once every 12 hours. It will dip within 120 miles of Mercury’s surface at its closest point, and go out to 9,320 miles at its farthest.

The orbit goes nearly pole-to-pole, offset by about 7 degrees. That slight tilt is to help get a handle on the planet’s gravitational field, said principal investigator Sean Solomon, a planetary scientist at the Carnegie Institution of Washington, in a press conference March 15.

Measurements of the gravitational field “will tell us something about Mercury’s composition, the size of the core and the structure of that core,” he said.

One of the mission’s main objectives is to figure out why Mercury’s core is so big compared to the cores of the other rocky planets. Another is to make high-resolution maps of the whole planet, some of which has still never been seen.

“Many on the science team have been involved from the very beginning,” Solomon said. “We are extremely excited to begin that mapping.”

Scientists also plan to search for water ice in craters at the poles which, despite Mercury’s proximity to the sun and scorching daytime temperatures, are stuck in eternal freezing shadow.

The spacecraft’s seven science instruments were turned off for orbit insertion, but they will reactivate March 23. The first orbital image, planned for March 29, will include some uncharted regions near Mercury’s south pole.

The science phase of the mission will begin April 4. The Messenger team will release data to the science community at six-month intervals, but will release images at least once a day throughout the mission, Solomon said.

“In addition to the global imaging we’ll be doing, we’ve targeted more than 2,000 areas for ultra-high-res with our narrow-angle camera. Many of them were not discovered until flybys,” he said. “We’ve got a long list.”

It’s time for English teachers to stop teaching that the earth is flat

18 Mar

Tweet

By Dennis Baron


When I asked a class of prospective teachers to discuss the impact on students of prescriptive rules like “Don’t split infinitives,” “Don’t end sentences with prepositions,” and “Don’t use contractions,” one student ignored the descriptive grammar we had been studying and instead equated correctness in language with intelligent design:

I think I support prescriptivism. I believe that some words are absolutely unacceptable in any situation. I think there should be an accepted way of speaking and deviation would not be tolerated. I believe in a set of absolute values. I believe there is one right and wrong for everyone. Perhaps what I think is right is not what you think is right but in the final analysis that isn’t going to matter. What God thinks is right is what really matters and He doesn’t have one right for you and one right for me.

Her faith-based answer, God speaks standard English so you should too, may be extreme, but her emphasis on correct language is one that too many English teachers accept without question. So far as grammar lessons go, it’s time they stopped teaching that the earth is flat.

Even though creationists attack evolution as “just a theory,” high school biology covers the origin of species, along with DNA, microbes and the circulatory system. Physics teaches the big bang, subatomic particles, and as even Galileo knew 400 years ago, an earth that moves around the sun. And students in chem labs aren’t turning lead into gold, except perhaps at Hogwarts. There are no fundamentalist wingnuts enforcing the view that the rules of English are written in stone, yet English teachers act like the study of language hasn’t advanced since eighteenth-century grammarians started making lists of good grammar and bad or decided that a noun is the name of a person, place, or thing.

It’s not that English teachers don’t know that linguistic knowledge has progressed over the past 250 years. Prospective teachers get a healthy dose of sociolinguistics, transformational grammar, and the history of English. They study the emergence of dialects and the social contexts from which language standards grow. And they learn that unlike the standard meter or kilogram, which can be measured with scientific precision, there is no single, objective standard language which everybody speaks. They study language contact, assimilation, and heritage language loss, and they learn that when schools abandon bilingual education and leave non-English-speaking students to sink or swim in English-only classes, most sink. And last but not least, they’re taught to regard their students’ language not as something to be constantly graded and corrected, but as an energetic, highly-competent, continually-evolving form of language, complete with its own standards and variants.

But when they get their own classrooms, many of these same teachers reject such knowledge in favor of the simplistic language model they absorbed when they were in school, a model that ignores the complexities of the language people use every day in favor of a few prescriptive rules that can be memorized and tested, but that have little connection with what really happens when we talk or write.

Galileo, sitting in a science class today, would be mystified by a curriculum that has gone way beyond his experiment with an inclined plane, but Apollonius, the 2nd-century CE Greek grammarian who was one of the first to write about the parts of speech, would be perfectly at home with a modern grammar lesson, assuming he could follow it in English. And speaking of immigrants, if we could actually transport Apollonius and Archimedes, the Greek mathematician who first described the principle of buoyancy, to the local high school, they might find themselves sinking in an English-only immersion program.

For years linguists have been trying with little success to bring school grammar back to the present. We’re not proposing to do away with notions of correctness — ideas about appropriate usage form an important part of the way that English speakers function. Instead, we’d like to transmute the conventional right-wrong language dichotomy into a contextually-dependent sliding scale of language that works in particular situations, and language that may not work so well, demonstrating that there are many varieties of standard English, not just one. Plus, we’d like to point out that even in an English-speaking country, the language people use doesn’t always have to be English.

Unfortunately our schools have always been too focused on enforcing and testing a monolithic model of standard English to encourage teachers and their students to explore the language phenomena that surround us. As a result, teachers find it easier to tell students simply to avoid the passive voice than to get them to understand that although the passive can be problematic, it’s often useful and sometimes mandatory.

But even with the simplistic rule, “the passive should be avoided,” it turns out that many students can’t figure out the difference between the passive voice and the past tense. So in the end, standard English, which may or may not actually exist, often remains a mystery, and too many students leave school convinced that whether or not language is the product of intelligent design, its design is far from intelligible to them.

Luckily, outside the classroom things linguistic are neither obscure nor monochromatic. It’s true that when put on the spot, most people will parrot what they learned in school, that there’s a right and a wrong way to speak or write. But mostly people take a practical approach to correctness in language, recognizing as correct what works in a given context, not what’s categorically good or bad.

Perhaps the most important grammar lesson to learn, then, is to trust our language instincts instead of mimicking some ideal which turns out to be a moving target. We need to finally leave the eighteenth-century prescriptions behind and aim for language that is simply good enough to do the job of expressing whatever it is we need to say. And when we study language, we should study what it is, not what someone thinks it should be.
