I still keep a tab open to the "off topic" board here. I check in most days to see what's up. Back in the day, I used to hang out in a number of other equivalent single-interest chat forums around other hobbies of mine, but I've left all those behind and still hang out here.

That said, I'm friends on Facebook and G+ with various subsets of the crowd here, and if we ever truly were going to kill off this board, we could consider replacing it with one of those. (Will G+ be long for this world? It wasn't particularly mentioned at all during Google I/O.)
