My content mandate -
If I give you my content, I expect in return: access to my content via RSS/Atom/XML/API/webDAV/etc -- something/anything in addition to the simple html view of my content.
By "you" I mean any website, webservice or web-enabled repository.
Luckily for me, most of the sites that I give content to already subscribe to my mandate! w00t! (del.icio.us/flickr/upcoming.org/blogs (roller)/etc.)
Hooray for the internet!
