That is a seriously good concept. Your metric works too good though, compared to the refresh rate of the listings so all the good stuff is sold out. If you had a mailing list I would definitely subscribe.
Thanks. Yeah I thought about a mailing list, but couldn't think of a way to make it not spam you every single day for the 1 or 2 best listings. But obviously can't aggregate them unless it's a digest of "here's what you missed," which would be slightly amusing.
