In reply to Andy M..

That's an interesting idea. I'd like to browse a site like that just to see what that one thing in WP is that is making people so upset. Outside of forum posts, ideas, blog posts, and Twitter there is no method to just outright make an angry complaint against WordPress.

I think the data could be valuable as long as the Kvetches reset after a major version or two of WP is released so they are relevant.
