Few weeks back I used Dave Winer's River2 to create WebJives NewsRiver. It's an app that runs in the OPML Editor (again developed by Dave Winer) that implements a River of News aggregator. Dave has enabled to upload the River on Dropbox enabling you to publish your river news. River2 has changed how I get and read my news. WebJives News River currently tracks 35 Tech/Media Blogs/News sites.
