Polihackery.
Cam Barrett showed me some of the community network stuff he's planning for the Clark Campaign yesterday, and I'm impressed. When I look at efforts like these, I see citizen choice in campaign politics evolving from support to inclusion to participation. We've been seeing this in the Dean Campaign too, of course; but I think now we're starting to see candidates trying to compete by doing a better job than the next guy of enabling, and not just fertilizing, their grass roots.
It's also interesting to see a political blog that's also a tech blog. Yesterday evening (about 7 hours ago, as I write this) Cam put up a post about the campaign's Shiny New Server and Open Source Technology. It has 250 comments so far, and it's only been a few hours.
By the way, Cam's tech team is recruiting right now. They need to fill at least four tech positions.
