"“Wellman is finding that Twitter isn’t flat,” Vidantam says—as if Tom Friedman’s chimerical “flatness” (the analytic value of which has proven to be nil) is the only possible quality of transformative political agency.

In last year’s revolutions, it wasn’t flatness that gave social media its power. It was its hyperlocality, its novel blending of intimate communities and witness at a distance.

Other work in which Wellman is involved argues for the richness of real-world community life that gets instantiated in Twitter. In a paper called “Imagining Twitter as an Imagined Community,” Wellman & his coauthors find that Twitter networks are “the basis for a real community, even though Twitter was not designed to support the development of online communities. There they conclude that “studying Twitter is useful for understanding how people use new communication technologies to form new social connections and maintain existing ones.”

Here’s the thing: Twitter is part of the “real world.”"

"I'm not saying that the only people capable of describing or critiquing classroom teaching are classroom teachers. There are people who don't work in a classroom who know a lot more about my business than I do. I'm saying it's difficult, as one of public education's foot soldiers, to do much with inspiration. I don't have many places to put inspiration, certainly not as many as the edtechnologists walking away from TEDxNYED minds buzzing, faces aglow, and so it tends to settle and coagulate around my bile duct. It's too hard to forget that tomorrow I and three million others will have to teach too many standards of too little quality to too many students with too few resources. What can you do with this?"
