If you follow SO/MSO you will notice an event in the Community Bulletin:
If you read up, SE has made some changes to the close queue in hopes to motivate close voters to... review. In the efforts they have fuzzied the numbers of items in the queue, made advertisements for rather obscure tags, removing in batchs items with no/less reviews from the queue, plus some other improvements, to get people reviewing. Now, we have +200 users with +3K reputation, ergo access to the close votes review queues, but even so questions sits there for a good while. What you think it can be done to get users review tasks in the review queue?
BTW, the current performance of SO is awesome, they triplicated the amount of reviewers, review tasks and completed reviews:
Since I posted this challenge, 15,137 reviews have been done in the close review queue, and a total of 6,829 review tasks have been completed.
