Matt Yglesias, Atlantic reporter and uber-blogger, announced last night—after his news was outed by colleagues—that he’ll be leaving the world of journalism for the nearby-yet-also-worlds-away realm of the think tank. The Center for American Progress, to be precise, where he’ll be working on ThinkProgress and its affiliates.

“I think CAP is a great organization, I miss the sense of collegiality that comes from working with like-minded colleagues on a shared enterprise, I think I can help advance their mission and when it turned out they felt I could too and were willing to make me an attractive offer, I was thrilled to take it—no beefs with existing employer required,” Yglesias writes.

As Andrew Sullivan adds, “He wants to be more committed to the causes he believes in than an independent journalist can be, and so I respect his decision.”

Yglesias will keep his blog, whose content will stay pretty much the same—“the blog will have a different URL and a different design so it’ll fit in with the ThinkProgress family, but the blog has changed URLs and designs several times in the past so that’s nothing new.”

Yglesias-and-blog will make their official move over to ThinkProgress in early August.
