Ask YC: Feedback for our new startup

The site is bidboxr.com We're getting ready to launch and since I've enjoyed so many of the articles posted here I thought it would be great to get some feedback from the YC community. Bidboxr.com is a unique blend of online advertising and online auctions. Instead of simply providing a site where sellers list items and bidders bid on those items, we've created an interactive ad banner that bring auctions to the bidders. One of our major goals when we created bidboxr.com was to provide online entrepreneurs/startups with a profitable source of revenue. Think of it like Google's adwords/adsense model, but we're using interactive auctions instead of static ads. The auctions are relevant to the content of the page, so it's designed to draw users who are interested in that particular content. Imagine reading a blog post about a digital camera and looking at an ad on the side of the page showing an image of the exact same camera on sale and closing in 10 minutes for $50 with a big 'BID NOW'
