It's unlikely that Facebook is trying to time their IPO at the height of their potential. I think they still have a lot of room to grow the display advertising business, but unfortunately there is a shift to mobile and the Facebook mobile UX isn't that great. I think they need to continue to worry about building products users love and improve mobile UX, advertisers will always come to where the users are.
