Actually, there's probably some website out there already that lets one solicit anonymous feedback. (Which would be a rationality boost for some of us in itself, even apart from calibration -- though I'd like to try calibration on it, too.)

Does anybody know of such a site? I spent an hour looking on Google -- perhaps not with the right keywords -- and found only What Others Think, Kumquat, and a couple Facebook/Myspace apps.

Both look potentially worth using, but neither is ideal. Are there other competitors?
