So, Matt Yglesias has decided to leave The Atlantic to take up a post with the content-creating wing of the Center for American Progress. Super interesting stuff. Matt was the very first political blogger I ever read -- whiling away those long recess hours in the Rayburn H.O.B., circa 2002 or so. He introduced me to the possibility that blogging could be a factor in the swirl of D.C. political life. Memorieeees... Anyway, it seems Matt's hungry to be more of an activist and an advocate than a journalist, but what's particularly intriguing to me is this line in his announcement post: "From a reader's point of view, this probably won't make a huge difference." As a writer/blogger with a big following, having the ability to pack up and move to a new URL is probably tremendously thrilling in a "f___ you money" sort of way. But there is a trade-off. First of all, you're probably not in as great a position to tap into institutional resources that way. And secondly, there's not as much tying you to your colleagues -- which is, in fact, one of the very reasons Matt cited for leaving The Atlantic for CAP.
