From Nicholas Carr’s Rough Type blog,

“Blogging seems to have entered its midlife crisis, with much existential gnashing-of-teeth about the state and fate of a literary form that once seemed new and fresh and now seems familiar and tired. And there’s good reason for the teeth-gnashing. While there continue to be many blogs, including a lot of very good ones, it seems to me that one would be hard pressed to make the case that there’s still a “blogosphere.” That vast, free-wheeling, and surprisingly intimate forum where individual writers shared their observations, thoughts, and arguments outside the bounds of the traditional media is gone. Almost all of the popular blogs today are commercial ventures with teams of writers, aggressive ad-sales operations, bloated sites, and strategies of self-linking. Some are good, some are boring, but to argue that they’re part of a “blogosphere” that is distinguishable from the “mainstream media” seems more and more like an act of nostalgia, if not self-delusion.”
