What’s so good and creative about Facebook now is that, it is created by young college students who know what are the “needs” for peer fellows, and word of mouth works the best among this group.
Big companies has more standards to follow and ecounter more pressures from the society. They tend to work under the power centralization, which might will lead to the ban of certain applications and functions on faceook.

Now Facebook is getting into some troubles because the deals with certain companies (allow advertisers to track what websites Facebook users had been to recently and advertise to the audience specifically.) Maybe in the future, it won’t be so fun anymore while a lot of things are banned, and who know whatever new fun things will come out~
