For all my whining about twitter, I did enjoy Ana Marie Cox’s live-twittering (tweeting?) of Joe Biden’s Amtrak speech today:

I’ll give this to Joe: He is speaking VERY PASSIONATELY (about Amtrak no less!) to a crowd of a dozen people (and twice that of press).I am about 99% sure that Joe is ignoring the teleprompter, just riffing on Amtrak facts he already has memorized. It is the awesome.Biden: “I’m going to leave before Sen. Rockefeller speaks–because I don’t want to listen to him.” I want the fulltime Biden beat. Love him.And Rep. Rahall (D-WV) provides us with the first train pun of the event! Apparently, “Joe Biden is just the ticket.”As fellow congressmen speak, Biden stays on stage, RAPT as they rattle off Amtrak facts. Nodding. Mouth slightly open.

There are few people in public life I like more than Joe Biden. But that said, trains are interesting! People should enjoy hearing facts about them!
