Personally I judge the posters by getting to know them and reading what they write rather than a number under their name or how many people agree / disagree, so I find it all rather redundant.
Definitely doesn't work that that in other communities I can say from experience.
If you run into someone with red bars under their name in Gotgames and Gametech (CSS) or 0% on CyberGamer, you know to stay away from them.
