There is no wonder that the rules of the game were dictated by big players, like facebook or google. They taught ordinary internet users (the mass) that good quality (usable and well-designed) services could be free.
So, if you trying to establish another service for masses it must be free, and meet the de-facto standards of quality. Tweeter is a good example.
It is possible to charge users for some very special and unique service, but only for a limited time, because free (no-cost) alternatives will emerge sooner or later.
It seems to me, that if someone wants to build such service he should think about some market-place or ecosystem (like in adult segment), not for public services for masses, because this market is already divided by rich and strong players.
