People said the same thing about myspace a few years back. It was king of the social internets. Clearly, it wasn't quite as big as Facebook, but it's all a question of giving users what they want. If someone can identify the discontents and innovate on them faster than Facebook can, then we'll see a new, legitimate, challenger. Of course, in order to do that, you have to think that FB won't innovate quickly enough to sit on whoever tries. It's the classic startup v. big company challenge.
