Blogging Roller

O'Reilly Network: The New Bloglines Web Services: "Bloglines today announced a set of new web services APIs, allowing developers to write applications for reading RSS and Atom feeds by drawing data directly from the Bloglines databases. This is a very significant change in the landscape of RSS/Atom aggregators, the newsreading applications that have become more popular over the past few years. Along with the release of its web services, Bloglines announced that several desktop RSS/Atom aggregators, including FeedDemon, NetNewsWire, and Blogbot, will begin using these APIs to provide additional capabilities in their applications. The Bloglines Web Services make it very easy for developers to use RSS and Atom content for many purposes, and the services will also ease the traffic."

A "very significant change" indeed. The coolest part of the article is a blog app: a 150 line Groovy program that implements a complete BlogLines newsreader.
