Technology in the Presidential Campaign

I'd like to see a session that talks about how the candidates have used the internet, and technology, to campaign in the 2008 elections. Blogs, videos, text messaging, community sites, fund-raising, etc... We've had a decade of elections with technology being a good tool to spread the word to the people, and it would be great to look at how it's evolved over time, how it will continue to evolve, and how it's being used right now, to get your vote.
