1) talking w/people at DigiPen, they mention 8 chan (in general, not specifically this board). Apparently this was around the time 8chan started being a notable thing.
2) this, /v if I have nothing better to do (a rare occasion), /christian for lulz + disappointment in humanity.
3) I don't browse much. I only peak here every few days for a few minutes/posts and that's more frequent than i do for most sites. it just so happens that /digipen is more relevant to what I'm currently doing than a lot of other things.
