Unlike Yahoo, Google has had a long standing resistance to offering RSS feeds for Google News queries. Hacks have long abounded from Julian Bond's GNews2RSS, Ben Hammersley's Google to RSS using the Google SOAP API, and Steve Rubel's advice in "RSS Hack for Sites That Don't Offer Feeds".
In this spirit, Justin Pfister has created gnewsfeed. Filling out the form uses a script that converts a Google news query (example) into an RSS feed (example). "I welcome anyone in the world," he humbly proffers, "to use it in an effort to become a more informed public."
Poor Justin. He's looking for a job. Maybe Adam Smith, and the Google Alerts product team will hire Justin to build in the syndication that Google should have offered long ago (hint).
