Yeah, the warning is weak sauce - I'd prefer something like this - but that'll have to wait.

w00t! You found a bug in my query, @damryfbfnetsi! Updated.

Sorry, I was in a bit of a hurry yesterday @damryfbfnetsi, and left out some of the details - see edit.

You don't like 2? What about 10? 50? The longer you wait, the more work someone has to do finding and retagging existing questions once the tag is created. Which, if you'll notice, mostly isn't happening. The most-used tag created in the last year was sublime-text-3 - and it had exactly one question in it when it was created on July 22nd, even though other questions had been previously asked about it. If you're gonna argue that fewer people should be able to create tags, then you gotta either have all the tags you need, or have folks willing to create them as-needed, @Ramhound.

As I stated in my answer, the reason for the low review cap is simply to give a broad cross-section of reviewers a shot at reviewing. The higher vote cap is to avoid penalizing reviewers for reviewing. @harrymc

That's not quite true, @CanadianLuke - if it was, we'd give you more reviews than close votes. What we don't want to happen is you blowing all of your close votes in /review and then having to flag problematic questions you run across. It is a good idea to salvage useful questions if possible, but in many cases it simply isn't.

Only takes one of them to make a big difference, @KronoS. Which is kinda the point.

Both SU and SO are 3K, @Dave (along with every other site that isn't in beta).

Probably a long-standing bug, but I can't be sure. You normally run out of reviews (limit: 20/day) before you run out of close votes (limit: 24/day), but today you hit the latter first.
