Hello, I was thinking that it might be interesting to add a -/+ or thumbs down/up for replies to posts. Posts with very high ratings could be highlighted somehow to make them stand out as useful/interesting/fun to read, while useless comments, trolls, flamers, etc. could have their posts down-rated. After enough down-ranks the post could be greyed out or minimized or something like that.
The point isn't for a popularity contest, but to help users sort through walls of replies to find the ones that are generally the most useful ones, and so that we can easily identify and skip posts that suck. (trolls, mean people, dumb people, people who post tiny useless things just to get their post count up, etc)
I think a feature like this would improve the mmo-champion experience!
