It's suddenly showing 178 new items to review, all of which are late answers, all of which seem to be posted years ago. I don't think it's a good idea if we start working on them, but if you aren't carefully checking the date you'll probably handle a few, which might bring the questions back to the frontpage for no reason.
A suggestion to have the reputation portion of the test that puts a new post into the Late Answer queue raised from 10 rep to 50 has just been implemented. This dumped many old “new” late answers into the queue from users who have 11–50 reputation. This is network-wide — fellow mods from other sites started asking about their review queues spiking, and that post's fresh [status-completed] tag was the answer.
It's by design, not a bug, but somewhat questionably handled. Fortunately, it is a one-time event and once the new backlog is cleared, it will return to normal, just with slightly more items to review per day than before.
On the plus side, this is an excellent opportunity to work towards some Reviewer badges!
