I get the feeling I'm more diplomatic offline. It makes it hard to gauge just how much people value certain things when you can't see them during a conversation.

Most of my personality is the same either way though, I do have a problem with feeling a (not particularly healthy for my own health) need to stick up for whoever I see as the underdog. IRL my size and intensity seems to make most aggressors back down pretty quickly, online I don't have that and I'm not as good with my words as some so it often backfires on me.

And yeah, I do have a tendency to occasionally go off on some random tangent online and off too, no idea what triggers it...
