In-depth useful comments are key. The best analogy is Amazon product reviews- the high-star rating serves as an initial screener, but the real test comes with the reviews. Positive but empty reviews are ignored, the useful ones talk about specifics of the product. Finally a quick glance at the negative reviews to see if they are about something substantial, or are just about a bad shipping experience or something.

This is a really interesting comparison to draw. What do you think of the 'movement' towards more transparent commenting systems like Disqus?
