After seeing the update to Is Clang/LLVM ready for prime time?, I'm wondering how to rate the other answers. A lot has happened between the moment when the question was posted, and the update. Most answers seem dated now.
I was wondering how to deal with a situation like this. Should we update votes? (if any were cast)
To me, the question itself seems to be very 'temporally localized'.
I don't think the update to the lead answer was a bad thing in itself, it's just such a stark contrast to a) the question and b) the other answers.
