You'll have to do a blog post on how you pulled it off some time.
Design feedback is going to be so friggin' easy from now on. If you ever begin to lose money on this, I'd love to buy a premium account or look into a subscription model.
(Regardless, you should look into a premium user program. Some ideas: prioritized bandwidth, custom shorturl for credit(?) such as //, a profile to save a history and metrics similar to URL-shortening services. No ads.
It'd seriously be stupid not to monetize this; I can't emphasize how much I love your concept.)
You could also reach out to companies looking for redesigns (or -aligns) and find a way to match them with a designer.
Remember to put up a link on Forrst. Heck, you could turn this into a design community by your own, where people share redesigns of sites - and you could implement a favourite and upvote system to reward the best ones. Showing users how shitty airline websites could look - not just as Adobe mock-ups - is very powerful. Set up some basic Django, include some thumbnails of each site link and implement a basic upvote and favourite system - boom, Dribbble for CSS. Scale later. Basically imitate all the monetization Kyle has done for Forrst.
As someone gravitating between college and no job, finding a way to prove my skills publicly is very difficult. This service would be great to leverage and would make it very easy to accomplish this feat. A premium user system could also allow people to include a pretty embed csspivot portfolio.
And then there's the whole let-me-show-you-what-I-can-do-for-you-application discussion[1].
If I were anyone on HN, I'd pitch him an offer for a banner on the site, because there's a very good chance that this blows up and goes viral. If I had a site or service to plug, I'd already have done this. Here is his Twitter profile, the only contact information I can see: http://twitter.com/metachris.
