On the heels of their success with Convention Hubs, C-SPAN has teamed up again with New Media Strategies to build online Debate Hubs. The first goes live tonight.

New Media Strategies’ Innovation Manager Bill Beutler points to a few new features this time around:

• The Twitter roundup is on the front page and auto-refreshes dynamically
• Debate Timeline visually represents the transcript – speaker and subject – it really needs to be seen to be understood
• Word tree visually represents which words are used the most and by whom

Video is still embeddable and clippable and, of course, the blog roundup continues (TMV was included there last time around).

They’ll be covering the debate in real-time tonight, and for each of the subsequent debates. Be sure to check it out.
