If the question is, is instagram worth $1B, I would definitely say, NO, from my point of view. But Facebook is more in tactical game than ever before. If you see, they have bought plenty of patents as well while they have bought instagram. They are focusing to dominate and secure every sector that we are thinking of. I guess, once Myspace had all the hype, but they didn't think what the next step should be, and here Facebook is going ahead all of them. With billions in hand, I won't surprise if they make several deals like instagram in near future.
