Well the title says it all. What if you have the option to click a little "Like" button on every topic post to show how popular it is? Maybe something like the reputation system? Especially when it come to support. Personally, I don't like the way how facebook gets to have "like" o mostly everything. So why not forums like this can have one?
See, back in the day, forums used to have a rating system. You could rate every post at one point(and you can see it still on some REALLY old posts). And it was abused. There was little point to it, and the forums became a popularity contest. The system's not likely to return.
