Zuck's announcement seems really thoughtful and authentic. He hit on a bunch of things people would be worried about -- whether things would automatically post, whether you can maintain a separate follower list from your FB list. He showed respect and humility towards Instagram's follower model, and interest in bringing it into other products. I'm impressed.
