Ive seen on some forums where there is a "Thanks" button. Its a system that if someone helps you or answers questions, you can "Thank" the person. This will build a good reputation and will also give credit when credit is due. I also believe it will help make more serious posts a little more reputable if the poster has a proven track record of being "Thanked".
Its just an idea... I googled it real quick and came up with this: http://www.vbulletin.org/forum/showthread.php?t=122944
