Tags are keywords or labels that categorize and group your question with other, similar questions. ('tags' wiki excerpt)
Questions related to size of Close Votes review queue at Stack Overflow are rather popular*, how to tag these?
Of existing tags, the following seem to apply:
review (1,5K+ questions in tag)
For questions about the /review path where users can view and act on posts by other users that the system thinks may need attention.
vote-to-close (900+ questions in tag)
Voting to close is the process by which users can vote to close a question if it is off-topic or otherwise disallowed by the FAQ.
stackoverflow (4K+ questions in tag)
Questions specific to stackoverflow.com and not necessarily related to other Stack Exchange network websites, such as retag requests.
Per my reading, these three tags together sufficiently qualify questions about CV queue size, while none of them alone appears to suffice.
Is one expected to use all three tags for this kind of questions?
For the reference: results of the search by combination of tags review, vote-to-close and stackoverflow.
