When a question or answer is voted up, the user who posted it will gain points. These points serve as a rough measure of the community trust in that person. Various moderation tasks are gradually assigned to the users based on those points.
For example, if you ask an interesting question or useful answer, it will likely be voted up. On the other hand if the question is poorly-worded or the answer is misleading - it will likely be voted down. Each up vote on a question will generate points as will each vote against.
Great answers start with great insights. Content becomes intriguing when it is voted up or down - ensuring the best answers are always at the top.
