I think it would be funny if you started out blocked by everyone since you are the owner, sort of a joke at Tom from Myspace.

And that's an interested idea, how do you think user growth will affect this model?

No idea. We are playing with it and figure it out.

Maybe you can get an initial block of 100 people to follow and have a "Give me 100 new friends" button which gives the user another 100 random people to follow.
