Eh, I may have refined my technique of argumentation a bit, but it's more or less just keeping fresh than anything. It's always been a particular skill of mine, and one I've developed in academia/my line of work. I will say I'm more witty online than in person, but that's simply because I have 15 seconds to think of a reply and post and that looks amazing whereas in person there might be an awkward silence, but I'm pretty sure that just happens to most everybody.
