I just bought a copy of Apple iLife 06 and created my first photocast of foodporn. The feed invents its own date format and places a
guid at the channel level. Apple is also doing some odd user agent restricting access to browsers such as Firefox and tools such as Feed Validator.

Perhaps Apple can publish an update to make all dates RFC 822.
Apple also declared a new “wallpaper” DTD that is undefined, just like their podcast DTD.
