Bloglines just launched web services, including the ability to access web feeds cached at Bloglines instead of from the source, a cool trick which normalizes the data formats and eases the load on the source servers.
Mark Fletcher talks about some of what can be done with the nifty new service and, in a press release, announced deals with FeedDemon, NetNewsWire, and Blogbot (no, not MSN Blogbot).
Geodog praises the innovation coming out of Mark Fletcher's world, and I have to agree. This is a great new feature.
Update: Marc Hedlund has an excellent tutorial over at the O'Reilly Network on using Bloglines web services.
