From tigerbeat's twittering:

There is a whole (fairly boring) GOP twittersphere including http://twitter.com/johnboehner Tom Delay only posted once. but where is nancy?

This is a small sign that we're making progress in at least one modern medium.

UPDATE June 26, 9:10 AM: Man, the liberals are getting pissed... even making excuses for Nancy because she's just "too busy" for twitter. Cleary, Oliver Willis has never used twitter. It's not really something you're "too busy" for. Further, Pelosi has at least one staffer dedicated to her online communication effort.
