I'm pretty much the same guy in real life. I think it's easier to tell when I'm joking about something in real life though. That's how the whole "Elfenwolfe's Trolling Acadamy Class of 2002" thing got rolling lol.
In real life, I'm much more likely to have a political discussion with someone.
In real life I'm a good conversationalist, although after a few beers, few people can get a word in edgewise on me.
I guess I'd say I'm a bit more subdued on the BBS than I am in real life. I think that my posts as a CM are a little closer to the normal, but that's only because I'm usually focused on communicating information, and not just BSing.
Interesting question though Sandman, thanks.
