The idea that partially-structured or unstructured Facebook could be a _serious_ competitor for a website that enforces some structure and provides services that can only work with that structure sounds a little stretch to me. It seems to me that the direction we are moving is towards more structured, purpose oriented websites that provide better services.
Yep. If you think in terms of the long tail, Facebook takes care of the people who have super generic needs on the spike side and they take care of the markets that are too small to pay attention to on the tail side but in the middle is a lot of space for competitors to do what you are saying and charge for a little structure.
