The new flag queue for 10k+ users is very interesting, but it lacks a crucial feature: Actually disagreeing with the flags shown.
Those who think a contribution deserves a flag, will add their own flag or close vote to the pile. Those who think the flag is unjustified, can do nothing except maybe upvote the contribution - which may not be at all what they really want to do.
Also, if I understand it correctly, questions disappear from the queue once they have been closed, so there is no way to review the 10k+ community's recent decisions.
As it stands, I don't think this is going to do good - it'll help a lot in the case of genuine crap of course, but it'll massively increase the number of unjustly closed contributions because it sends a huge mob (i.e. us) towards everything that got flagged.
Am I overlooking some hidden wisdom? How is this feature supposed to work?
