Half a year ago I raised a similar Meta post, and very fortunately the queues has been kept at a reasonable size (10~40) since then.
I just checked back here and WHOA!
The queue has far overtaken Stack Overflow's!
In the past 2~3 months I'm very glad to have seen new users becoming active and avid, as well as their generous help with this site by participating in the review queues. But it was only "the past few months", not today (and the near future, I'm afraid).
What happened to the queue(s)?
