I think it would be kind of cool if the reviews were sorted by constructiveness somehow.
Mabye it could be the number of experience points the reviewer submitting them has, or the number of blam/protects, or better yet, the number of responses from the author their reviews have recieved. That way, the more constructive reviews that the authors want to read would usually be at the top, and the generic "This rox please make more" or "This sux I hate u" reviews would get sorted to the bottom, because they don't really have much of a point.
Not only that, but it would inspire the flash authors to respond to reviews and be active with the community feedback and whatnot, while also inspiring reviewers to be constructive so they get more feedback and get their reviews bumped higher on the list!
What do you guys think?
