I don't.
I know this place is dead, but it's got the benefit of allowing me to post on various topics on the same website.
Prior to this, I used to hang out on Rooster Teeth (forget why I left), Sonic Anime Fans (again, forget why I left), and StarCraft Legacy. That er...well, let's just say that I was having fun until 2010, then SC2 was released, and I had five years of toxicity. I left just before LotV was released, as I was just so tired of everything.
I guess you could also include Wikia/Gamepedia forums, as I sometimes have to discuss things on the wikis I edit.
