I've noticed that close votes seem to have an endless backlog. On other SEs, this does not seem to happen as engaged users that stick around end up with the 3k rep needed to review these questions.
Given the amount of blatantly off-topic questions we get, it seems to me that we need more high rep users. It also seems to me that WPSE users are not too fond of upvotes which may be holding some otherwise helpful users back from fully contributing.
What, if anything, can we do to resolve these issues?
