The more interesting idea though, is that the newly added designers could work on an entirely new feature or service for Facebook. Last time the company brought in some big-name design talent, like Nicholas Felton, we got a major overhaul in the form of Timeline. Felton has since moved on, and it seems like its time to bring some new blood into the design labs. Who knows, maybe the new folks can make Home or Slingshot people will actually use. (But don't hold your breath.)

Update: This post has been updated to make clear that Facebook did not "acquire" the company Teehan+Lax. Instead the social network is bringing on the design team, but not purchasing the firm's assets.
