I flagged an answer as "not an answer" on April 28, since I thought it didn't really address the specific concerns of the question. (Whether or not that is true doesn't seem entirely obvious, now that I think of it, but that's not the point here.) I've been wondering about whether or not my flagging was correct, so I've periodically checked my profile page to see if this has been addressed.
But it's now May 7, and the flag still shows up as "pending" on my profile page. This, assuming it's not a bug, seems like a really long time. (For comparison: flags on Anime & Manga seem to get answered within a day. I flagged a question as "duplicate" at around the same time as I flagged the answer here on English Language and Usage, and that got resolved within a week.)
Is there any reason why this should be the case? To me, the most obvious reasons for this would be low or infrequent participation by users with enough rep to access review queues, and that seems worrying.
