Radovan - I think you and I agreed to disagree long ago on whether or
not the data format constituted part of the interface.  That said, I
agree it's valuable to not change even the data format in a
non-compatible way.

My switch to Atom was felt to be a compatible change because I waited
until most RSS consuming applications also supported Atom.  I never
heard a single complaint.

Mark.
