A lot of our growth recently has been on twitter, and we expect even more soon. We take a 3% cut on cash out. If A gives $1 to B and B gives $1 to C, there is no fee. If C cashes out, we remove our fee and any overhead of moving money in and out of the system. The worst case overhead ends up being a fraction of the overhead of just using paypal. We have already seen lots of P2P usage of this (paying for coffee or gifting a beer for a friend), and heavy use in microgiving donations to non-profits. As applications build on top of twitter, we expect people to pay for them using us. We've already made an API for these transactions: http://tipjoy.com/api http://tipjoy.com/api
