I'm sitting in the Austin airport waiting to board my Southwest flight to Houston and on home to BWI after a great conference at Netroots Nation. Who sits down two rows away but Libertarian presidential candidate Bob Barr. I went on over to ask what anyone would ask: do you Twitter for yourself?

Indeed, Barr says that he does twitter on his own. Barr joins the growing ranks of Twittering elected officials like John Culbertson and Tim Ryan. But unlike fellow Presidential candidate Barack Obama, Barr twitters himself. No staff, no help. (And that may explain why his tweets are a bit...off, at times.

So, congratulations, Congressman Barr, on taking the dive and Twittering for yourself. Have a great flight and and keep the tweets coming.
