haha i swear a lot more in real life...
As do I.
Overall, I think I'm mostly the same, but not quite. I'm probably more of an asshole online than in real life (though, I can be a huge asshole in person, too), just because there is a certain amount of detachment from "real life" that makes me feel able to push the limits of good taste more than I would offline.
My style of humour is probably slightly different online than offline, too. For example, I've made a few jewjokes and niggerjokes on GW that I would not make in real life, even among "trusted friends." Mainly because these jokes are acceptable on GW (in ironic sort of way), but not really in real life (people just assume you're a hardcore racist, even if you're clearly joking and/or being ironic).
I dunno. I think I'm pretty similar on GW and in real life, but I know there are some differences.
