I like the system they have on YouTube comments where you can give comments a thumbs up or thumbs down. I think that would be cool to somehow implement that into threads and posts on MacRumors forums. I know there is already a way to rate threads, but no one ever does because it's not easy to get to. Rather than a star rating system, it would work like the one on YouTube. For example, if 50 people gave a thread a thumbs up, and 5 people gave a thread a thumbs down, the score would be +45. The thumbs-up and thumbs-down symbols would appear to the right of the thread title, like the current star ratings do. It would also work on posts inside of threads. I think this would easily let people know which is a good or bad thread, based on user opinion. Here's a (pretty bad) mockup of what it could look like:
