As a group, we should focus on voting (both on questions and answers) as often as we can, for two reasons:
It raises the overall average score, unlike on SO where it is very difficult for a Mathematica question or answer to rise above 20. This was becoming less difficult as new users found the site. Also, there is a perception of "this post (q or a) has enough votes, so I'm not going to vote for it," and I'd like to try to avoid that mentality.
While in private beta, all privileges have a lower threshold than public beta, or launched. So, we need to boost people into the ranges wherein they can access the moderation tools. We will have pro-tem moderators appointed at some point after entering public beta, but they're are only 2 or 3 of them, and the rest of the community should be able to take some of the workload.
If a post is good, please vote for it. But, as always, vote your conscience.
