This is cool UX and I want to know who verifies questions marked
as duplicate.  share|improve this question George Stocker does.
Every single one. –  random Mar 17 '11 at 20:11 add comment  1
Answer  up vote 4 down vote accepted  Ultimately everybody who
uses the site.  Those with a reputation score of 3000 or more
can vote to close, but anyone with at least 50 points can add a
comment with a link to a duplicate and absolutely anyone can
flag a post for moderator attention.  Then, when a question is
closed other users can vote to reopen if they disagree with the
original decision.  share|improve this answer add comment  You
