I feel that this is also because of the tech world is still watching who's going to build the "Facebook killer." There are many companies that tried but I think the fact that they are contemporaries of Facebook already put them at a disadvantage. If Facebook is to be displaced, I don't think it's going to happen with its current-generation user-base of twenty-somethings. Whatever it is, it'll probably take off by acquiring today's teens as the main user base. That's why it's important to observe their social networking behaviors.
