Unsubscribing from the publisher's side
Dave Winer raises some good questions about the proper way for those who are publishing XML feeds to force unsubscriptions for readers, and Nick Bradbury points out a fairly clean solution that has the advantage of already being implemented in the wild.
Publishers should simply an HTTP Status 410: Gone code, and the aggregator or syndication client will know to do the proper thing and unsubscribe. The next version of Nick's tool FeedDemon is scheduled to add this support.
