I really find it surprising that your site apparently has 380 BTC in reserves, and 274 LTC or so alongside a few thousand dollars in Paypal funds, yet you guys cannot afford to pay a better designer to do your site design.
It's not compulsory, but I would like to see a signed message from any of your bitcoin cold storage addresses that holds more than 100 BTC. This would greatly boost the public's trust in you as well.
Your ANN is way too brief to make an impact on the advertisement side of your site as well.
There's a ton of automated exchangers out there, so you'll have a great deal of competition. You'll need to have lots of advertising before your site actually takes off.
