Wow. Now this is cool. There's this web site called CommandShift3 (named after the keyboard command for taking a screenshot) that pairs two web sites against each other, and users click on the one they think is 'hot'. I entered CritBuns.com back in December 2007 and the stats are quite impressive: "Top 5% of sites (460 of 9924)"
See the listing, browse other sites, or enter your own site.
