I reviewed a question for the current iteration of the site self-evaluation back on April 23 (here's the link). I notice that the self-evaluation is still running. Isn't this kind of a long time for the self-evaluation to be active? On the other sites where I've used the self-evaluation queue, it's usually gone within a week or two.
I suspect that this might be related to this bug - there are 10 items in the self-evaluation queue, after all.
UPDATE: It's been running for over two months now...
