The New York Times checks in with the latest update on what’s going on with Tumblr, a growing link sharing community that is attracting some old-world media as well. John Mayer’s highly publicized “defection” from Twitter back in April 2010, garnered Tumblr some initial big splash, famously saying that “Twitter isn’t over, I’m over it.” It’s not quite reached the growth of Twitter, where its crashing servers left and right, but the format is mighty appealing, as it allows contributors to write as much, or as little as they like, and include pictures as well. Breaking free from a simply 140 character limit can be quite liberating, and users like Mayer hope that it generates more thoughtful discourse. Such stalwart media outlets like the New Yorker, the Economist seem to agree. Some more established restaurants, like In-N-Out Burger, have also mined the depths of their fan bases, letting fans post pictures and stories. Probably not long before Tumblr starts creating real waves.
