A butterfly flaps its wings, xkcd puts up a comic on ratings, someone piggybacks on the comic, it makes the front page of HN, you wander by and mention criticker, a bunch of geeks pile onto the site to check it out... and it ends up crashy for a while.

Cool site, thanks for mentioning it. From what I saw before it went down (too many mysql connections?), it even looks like I can export my ratings.
