I wrote last week about PA senatorial candidate Chuck Pennaccio innovative use of YouTube viral video to take on the Bush administration. Now another fascinating example of a political campaign using Web 2.0 technologies has come online.

Rocky Delgadillo is running for California Attorney General and just began offering an Instant Messaging notification service on his website to let supporters know about new developments in the campaign as soon as they emerge. Delgadillo is targeting corporate abusers in insurance, health care and environmentally destructive industries (ok, and gangs too) in his campaign. He's got a long list of prominent endorsements.

The notification system uses an RSS to IM monitoring tool called immedi.at - one of my personal favorites among Web 2.0 technologies. Though users never see the letters RSS, when Delgadillo's news feed is updated anyone who has signed up gets an IM ping with the link.

I wrote about RSS to IM and SMS tools in greater depth awhile ago over at MobileActive.org and I hope that more progressive and grassroots efforts will leverage these sorts of tools not just for mobilization but also for just-in-time research.
