What are Popularity Points?

If you haven't already noticed, there is a thing called "Popularity Points" here on UT Prep. Any time you comment on a page, video, or even post in the forums, other users can either vote the quality of your post up or down. Any time a user votes your post "up" you get 3 points. If they didn't like it, you just got -2 points. So long story short, the better posts you have on UT Prep, the more positive votes you get, which means you gain "Popularity".
