If there is a pointing system there will be people who abuse it. You can't create a "perfect" pointing system (at least it never worked out). Look at impact factors in science, page rank or anything else.
Having said that I really like StackOverflow. I didn't contribute to them ever but whenever I google some difficult question it's really often that a StackOverflow link is the first or second result. It may not be perfect but it is really a step forward compared to tech forums.
Nvm, I fixed it
I sent the solution in pm
Download this script from megaupload
Thread derailed / answers one or multiple different questions
