Now that we have graduated out of beta status, the rep requirement levels have bumped up to that of a normal site. This is expected, and a good thing. However, our users' rep levels are not high enough to self-police the community without moderator action. The root of this is caused by a low level of voting from the community. 75% of questions have 4 or less votes. 75% of answers have 2 or less votes.

Why is it important to vote on both questions and answers, and what are these votes supposed to mean?
