I honestly don't think it's much of a big deal to bring up old threads though. Exception is that it is kind of wierd to bring up some really old thread that ask for a question and then someone respond back like a 6 months later saying "yeah, get it". I mean 6 months go by, I'm sure they already made a decision on something.
