If you've been part of the site longer, you're opinion matters more than everybody else's? Why? If I think something has been helpful, I can give a little rep, but if AncientDragon thinks its helpful, he can give a whole ton of rep because apparently, he knows better than me. And then there's the issue of High rep users being scared to vote because they have so much influence...
(This is a little strong worded and I mean no offense at all, Daniweb is an awesome site, it was just to help get the point across. :D )
