Hmmm... deep question. I'm pretty much the same, only here you can't see me making funny faces.
Seriously though, the only thing that's different about me here is that I'm less outspoken. If I believe something I will argue for it, but I won't go crazy. My outspokenness has gotten me in trouble before, and it's good that here I have time to think about what I say before I click the little "Submit Reply" button.
