The question then becomes how can you make a website with all your friend (and by association all their friends) make enough profit to run itself?
Early Facebook was kind of a great mix. It had enough people on it, it was making money, and the advertising was much more reasonable. At the time it really was a place to connect with IRL friends.
You mean, how can my friends and I fundraise my $3 VPS? It's going to be rough, but I think we'll find a way ;)
(If we hit the stretch goal, we can upgrade to a raspberry pi!)
