One problem other than convincing people to use it is convincing people to pay for it.

If we don't like Facebook's business model of using user data to make money we'd have to charge people to use it, and not a lot of people would be willing to do that.

Of course, one could argue that it's possible to make money with user data without being evil, but no one seems to have managed to do that so far. I bet if this project became as successful as Facebook it would be hard not to end up in the same exact spot.
