I feel like most of us do; at one point or another I've probably had like 20 different tabs open, spread out through all the boards and forums and sub-forums we have. Hell, sometimes I even had the same thread open in 2 different tabs, because I wanted to read something from an earlier page or whatever.
That doesn't mean I don't have a forum I frequent more than others, though. Probably back when I first started, that would've been the TCM asset submission thread (aka I had no idea how the hell a forum worked and only knew that one particular thread existed) and, later, sprite and art request threads. I migrated over to PRP and General RP sometime after that, then forum games, then... probably back to RPing? Currently, I probably spend most of my time in Small Talk and the News section whenever I am on the forums, but the site's grown so much I find myself spending more time looking through everyone's profiles and scrolling through the Creative Corner (do we have a semi-official nickname for that yet? CreaCor? CC?).
So yeah, I hope that answers the question? ^^;
