Not that long ago, I was at a conference at Yale and looked at the sea of open laptops in the seats in front of me. So why wasn’t my laptop open? Because I follow people on Twitter who serve as my Web-crawling proxies, each of them tweeting links that I could examine and read on a Blackberry. Regardless of where I am, I surf far less than I used to.

The best people on Twitter communicate with economy and precision, with each element — links, hash tags and comments — freighted with meaning. Professional acquaintances whom I find insufferable on every other platform suddenly become interesting within the confines of Twitter.

the ethos of Twitter, which is based on self-defining groups, is far more well-mannered than many parts of the Web — more Toastmasters than mosh pit. On Twitter, you are your avatar and your avatar is you, so best not to act like a lout and when people want to flame you for something you said, they are responding to their own followers, not yours, so trolls quickly lose interest.

“Anything that is useful to both dissidents in Iran and Martha Stewart has a lot going for it; Twitter has more raw capability for users than anything since e-mail,” said Clay Shirky, who wrote “Here Comes Everybody,” a book about social media. “It will be hard to wait out Twitter because it is lightweight, endlessly useful and gets better as more people use it. Brands are using it, institutions are using it, and it is becoming a place where a lot of important conversations are being held.”

I have found transcendent tacos at a car wash in San Antonio, rediscovered a brand of reporter’s notepad I adore, uncovered sources for stories, all just by typing a query into Twitter. All those riches do not come at zero cost: If you think e-mail and surfing can make time disappear, wait until you get ahold of Twitter, or more likely, it gets ahold of you. There is always something more interesting on Twitter than whatever you happen to be working on.

As news outlets were scrambling to understand the implications for travelers on Saturday morning, Twitter began lighting up with reports of new security initiatives, including one from @CharleneLi, a consultant who tweeted from the Montreal airport at about 7:30 a.m.: “New security rules for int’l flights into US. 1 bag, no electronics the ENTIRE flight, no getting up last hour of flight.” It was far from the whole story and getting ahead of the news by some hours would seem like no big deal, but imagine you or someone you loved was flying later that same day: Twitter might seem very useful.

Companies are demanding more of employees. They really want them to have a broad set of skills.”

But the major isn’t nearly as important as the toolbox of skills you come out with and the experiences you have.”

The virtual tutor takes care of the basic concepts that typically dominate lectures, leaving professors open to plan the face-to-face component of the course according to what parts of the curriculum the software tells him students are picking up more slowly, and what concepts could bear reinforcement. For example, if a statistics professor notices in the data he receives from activity in the open-learning program that a great number of students struggled with the assessments the program gave while teaching conditional probability, the professor could use the class periods to hold a discussion with his students about that concept until he is confident they get it -- a preferable alternative, Thille says, to rolling through concepts didactically and hoping they stick.

Lectures and the classroom spaces built to accommodate them, she explains, represent academe’s first attempt to do higher education at scale after new waves of students started flooding into America’s universities following World War II. With technology having evolved to its current state, such a method is primitive, she says. “You have this poor faculty member,” Thille says, “who’s sitting there as an expert in their area trying to figure out how to transfer their expertise to this large number of students, who are all variable. And it’s a horrible task. The affordances of the technology and also the learning sciences… for the first time enable us to really think about how to scale in a much more effective way, so we truly can serve many many many more students."
