With the Atom 1.0 specification finalised, I've decided to drop support for RSS completely. Once Movable Type 3.2 is released I will be upgrading my Atom feed to 1.0 from 0.3.

I have already removed the RSS feeds, but for the next few days/weeks Atom will still be a 0.3 version.

UPDATE: I am only supporting Atom 1.0 now.
