We need a service to seed social sites with users and contributions.<p>This could be done by paying people or perhaps just agreeing to seed each other's startups.
The best is if you take your seed money from a guy whose rich enough to fund you, but poor enough that he spends all day submitting stories from fake accounts to make sure he doesn't lose his investment. :-)
So reddit faked their early users... even though they had pg's readers. A new social site must get really creative if they consider faking users not ethical (as I do).
