In person I guess I'm a bit more toned down, especially in my work-life. I'm just as geeky, just as noisy, I swear just as much, and I argue just as much outside of EoFF as inside.
I'm not at all sexy. But I'm funny.
EDIT: I thought of one definite way I'm different online than offline. I am really, really bad with men in person, but most of my friends here are male. That's weird.
