I want to help review. When I go to the review page, and it says there are some items queued for review, it seems like 90% of the time when I click a review category, I'm told "The queue has been cleared!" I keep going back to the Reviews page, seeing there's something to review, but then ending up unable to review anything. It's very frustrating!
It seems to me that the top-level Review page is accurately telling me there are items queued, at the time the page was rendered, but then I guess other people are beating me to the punch on those queued items.
And it seems to me that there are so very many items coming into the queues (at least for, say, First Posts), that it warrants the following suggestion:
On the "queue has been cleared" page, have an option to "wait for another item to be queued," whereby I can sit back and wait for an item to be assigned to me, rather than having to manually go back and forth between the top-level Review page and a category page until I get lucky. If an item is assigned to me and I don't review it in, say, 2 minutes, then take it back away from me and re-queue it.
