It seems to me that voting on this site is particularly low turn-out. That includes question and answer, and both up and down votes. As a very quick exercise, I just looked at the top few on the "active" questions page, and the median number of votes on an answer was 0. In fact only one answer had any votes at all! (Coincidentally or not, it was answered by a mod.) These questions have views, so they are not sitting there waiting for a first look.
This seems to reflect and/or cause several problems that are reflected in other threads on meta:
There seem to be a lot of low quality questions and answers that really should be downvoted so that the good content can rise. (Not to mentioned flagged, marked duplicate, etc.)
There seem to be a few good questions and answers that don't rise because they sit at 0 votes perpetually.
New users cannot increase their reputation, so the review queues (as I understand it) are getting back up with the handful of users who are both active and high rep at the same time that natural attrition reduces the number of high rep users who remain active.
The system seems to be bringing old questions to the front of the queue. ("Bumped to homepage by Community.") I infer that this is happening on questions that have one or more answers where none of the answers have votes. This further mucks up the works by bringing back questions that (apparently) no one cared about in the first place in an environment where we're already not getting enough quality questions in the mix.
Any ideas why there are so few voting members here? I understand that review queues require reputation to access and time to review. Voting requires only a single click on something that you've potentially already read anyway. It doesn't seem to be as big of a problem on other sites that I use, including some fairly small ones.
