Ask HN: Review my startup, passubuy.com

My team and I recently built a browser-based platform for sharing items to sell with the user's Facebook community (friends & friends of friends).

The general idea is this: Through the power of Facebook, you post something you want to sell to your network of Facebook friends. If it looks good to them, a friend can buy it and you make your money. If it looks good to a friend but they don't need it, maybe they know a friend who does who they can pass the posting along to. If it sells, you still make money, but your friend who simply passed it along also makes money! Sales only occur between friends or friends of friends (or friends of friends of friends, etc., get the picture?), so you can always trust the transaction in a way that you never can on the "other guy's list." And anyone who helps pass a posting along that ultimately sells gets a cut!

I'd love to hear what the HN community thinks.
