I finally made the jump from Radio Userland’s news aggregator to NetNewsWire last night. It’s good software, and it’s been fun watching how quickly it has matured. I have about 40 RSS subscriptions, but I migrated to NetNewsWire in just a few minutes by dragging the XML links from Radio into NetNewsWire’s subscriptions pane. The app has really embraced interoperability. Brent has also proposed a common RSS clipboard and drag-and-drop format.
