I just cast a closevote (duplicate) on this question, which at the time had no comments, answers, or votes.
As I write, it says Marked as duplicate by FumbleFingers 2 minutes ago, and there's an answer posted 1 minute ago.
The question does seem to be closed. But I'm not a mod, so how come the system didn't wait for 4 more users to closevote before doing this? And how come an answer was accepted after it was closed?
Have I just been granted "superpowers", or is there a bug in the system (perhaps relating to the answer being posted seconds after my closevote)?
EDIT: (having been enlightened by @tchrist). I've just posted an answer to Provide visual prompts to actions of regular users when they exercise superpowers. In the absence of a visual prompt as requested, I don't actually want this "superpower".
I'm not going to devote huge amounts of effort to making sure I use my unilateral closevote powers any more carefully than I used my normal "1/5th of a closevote" power. I can't even be bothered to keep tabs on which particular tags I'm empowered for, let alone keep checking the questions to see if they happen to have those tags.
So before there'e a kerfuffle about my pending imperious behaviour, you might wish to consider adding your vote to that meta.meta feature request.
EDIT2: Apparently the links I was given earlier about this subject all end up on Stack Overflow's meta. But since my complaint involves a site-wide feature, it's more properly addressed on meta for the entire network (where currently my complaint just has one uncommented downvote, so I feel could use some support! :)
