Bloglines, a Web-based RSS newsfeed aggregator, today announced new application programming interfaces (API) and Web Services to help reduce the bandwidth demands on sites serving syndicated feeds. “Now, instead of thousands of individual desktop PCs independently scanning news sources, blogs and Web sites for updated feeds, Bloglines will make low-bandwidth requests to each site on behalf of the universe of subscribers and cache any updates to its master web database. Bloglines will then redistribute the latest content to all the individuals subscribed to those feeds via the linked desktop applications — FeedDemon, NetNewsWire or Blogbot — or via Bloglines’ free Web service.”
