The business model can't be "become a giant social network that makes billions and employs tens of thousands of people."

If the whole thing is lean, with minimal costs, no account reps, and essentially non-profit, it's a lot easier.

Of course, that means it goes one of two ways:

1. Never gets traction, dies after a bunch of work

2. Takes off and the people controlling it (rightfully) want to be compensated for their hard work, so they start adding advertising and focusing on monetization, which requires hiring more people, which requires a more mature business model, which heads towards IPO.
