OK, I'm overstating it, but please check out the great comments on my previous post regarding wine.woot! and the newly-launched RadCru, including comments direct from the heads of woot! and RadCru. Tim Elliot of winecast provides some terrific economic analysis, and Paul Mabry of Inertia hopes to see a thousand flowers bloom.
Thanks to everyone who has commented thus far for adding substantially to my original post.
