The ability to invite people would be nice.
Most of my friends willing to take a chance are internet friends.
My rl friends are skeptical, they think i'm on the fringe, anyways.
If the place doesn't float on it's own merits we need to adjust something in the design.
Not attack our potential contributors with fees.
Just getting to screw the credit card folks out of their processing fees should excite a large percentage of the population, perhaps we should highlight our positives?
