Clean, easy to use. Needs a better directory, or categories of what is available. After 48 hours of tinkering, I like it. Adding an auction feature would definitely start cutting into eBay/PayPal's monopoly.
We have created a listing offering escrow/mediation service. Just search for CoinPro under listings. We will rebate the .0015 to the first 20 users that leave positive feedback.
The problem with a decentralized auction is, that the winner doesn't have to pay. You will have a lot of auction crashers. The people who really want to buy stuff will hardly get them. I mean, you even can write a script, that always offers 1 $ (edit: sorry 0.000whatever BTC) more than the last bid at every listing. Kind of OB DDos attacks for the lulz.
