Quite so. Facebook has made a bonanza on new internet users. My personal belief is that most of these people will figure out that Facebook is not the internet and spread out to other services, decreasing Facebook's importance, and they will not be replaced by other new users in the similar quantities. And yes, the past three years have shown derivative introduction after derivative introduction. Facebook is basically in it's MS-1998 stage: if you can't buy the competition, copy them thoroughly and use your superior market power to smother them. This will end up just like MS, in a dying, boring irrelevant company that has a popular product, but absolutely no clue about where to go next and a serious inability to catch on to true trends.
