The great Teehan+Lax agency is shutting down, and its leadership is joining the Facebook team:

We have made a big decision that in 2015, we will join Facebook and the Facebook Design team. This is a significant move for us, professionally and personally.

Good news for the partners, but what about the rest of the company? From the outside it is difficult to tell the full story, but the appearance is that about 40 people were let go as a result of the move.
