I haven't read a whole lot about your guys' operation, in fact I didn't even know the content was user submitted, but I'm wondering how you're moderating content for quality. I ask because as I was checking out the site last night, I was noticing typos and grammatical errors here and there. There are also technical downfalls, which are probably not as easy to fix.

If anything, a lazy way to get information on this would be to 'robustify' the feedback tool. If I notice a typo, or a bug, am I happy? No, not really. But I'm not confused either. The feedback tool should also act as a quality assurance tool IMHO.
