In a big indication that we're only beginning the social revolution for politics and that RIAs will play a big part, CurrentTV is going to be doing live streaming and a real-time overlay of Tweets using Flash. The broadcast will be available on the CurrentTV Hack the Debate site as well as a number of regular TV broadcasts with Flash powering the Twitter visualizations.
We're seeing a huge explosion in the use of rich media during the election. We saw an example with Silverlight being used to stream the Democratic National Convention live and now we're seeing what I hope is a big trend - incorporating other data into the live streams. The power of using rich media in RIAs goes hand in hand with how much extra data we can bring in. That's what makes it so much better than TV: we've got the web at our fingers! Why shouldn't that be more interactive? This is a good first step, and I hope we see more down the road.
To participate all you have to do is tag your Tweets with #current and it will show up during the debate. Now if only we could get a backchannel that the candidates actually looked at and responded to.
