I believe I have my nerdy twitter account linked onmy profile. I mostly use it to follow some podcasters as well as the myth busters and wil wheaton.
I think it would be a great way to take notes and photos for battle reports, however. I'm hoping to practice that my next couple games, and then transcribe them to more of a blog post. Just another thing on the to-do list at this point, though.
