There’s a lot of stuff written about Twitter and most of it rubbish, but every now and again I read something that really sums Twitter up nicely. This piece by David Carr in the New York Times is one of those great articles that talks very clearly about why Twitter is both useful and important, but without flipping out in gushing hyperbole. It’s the sort of thing that I’ll keep in my arsenal of articles to show people who want to understand social media.
