According to the badges page, there has been 1 silver and 1 gold badge awarded for the
[regex] tag on Stack Overflow. So I said "congrats" to the guy who's gotten 1000 upvotes for regexes, then clicked to see who it was.
I clicked on the silver badge. It's Gumbo!
Then, for some reason, I clicked on the gold badge. It's bobince!?
How does bobince have a gold regex badge but not a silver regex badge? Isn't that kind of impossible? Shouldn't there, by definition, be two people with silver regex badges, bobince and Gumbo?
Just to verify, litb and paxdiablo have both the C silver and gold badges, and Peter Hosey has both the silver and gold Cocoa badges (badges chosen because of the small number of users to verify, and also I just got the C silver badge so it was on my mind). What gives?
