I think it would be useful to have a service that would provide an IMAP style API for others to consume. This service would manage my subscriptions and maintain information about read/unread status, starred items and so on. The benefit would be that I could easily use different reader applications/services, for example depending on the device I'm using or other needs. This would also make trying out new things, such as the Newsblur much more convenient.
