Ars pointed me to the C-SPAN debate hub and while I didn’t use it during the debate, I have to say it’s a site worth a look. There’s a lot of information on the page, but it seems pretty well designed to me. It includes video and transcripts from segments from the debate, twitter feeds, blog posts, infoporn about what the keywords were during the debate and who spoke when. I’ll definitely check it out during the next debate.
C-Span has come a long way since the flap about videos of Colbert at the press club.
Edit: Looks as though The Current is trying something similar.
