SEP 15: Switch to RSS for feeds (currently using Atom)
I like the specification for Atom Feeds, it is both reasonable and thorough, as any good spec ought to be.
I have only one problem with the Atom specification and that is the requirement that all feed elements have a title attribute. WHY?! Only a subset of documents require a title. This requirement is completely deaf to the needs of micro-blogging and more ephemeral/transient short form content.
Dave Winer believes similarly that feed elements should not be required to have titles.
