ATOM

Blogger only supports Atom XML syndication feeds. There is no official explanation for this and it seems kind of premature since the spec is only at 0.3 (and has been for a while) and is missing a great many things (like widespread aggregator support). For example, an important part of RSS is extensions. Here I quote the full section of the Atom Spec on extensions:

7  Extending Atom [[ ... ]]

If you can generate Atom, then generating RSS is trivial. So it must be for some political reason which is fine but as an end user it makes using Blogger with other tools is a total pain in the ass. As a developer, supporting 2 totally different syndication formats is something I don't really need. At this rate, I'll have to look into supporting HTTP error code 448... The interesting thing about Atom is the support for a SOAP based posting / management API that would work across different platforms. This, however, has nothing to do with the syndication format. Update:Dare Objasanjo points out that if the 0.3 ATOM spec which everyone is racing to implement (the one that says DON"T IMPLEMENT THIS is not compatible with the 1.0 spec then there is going to be a user issue. Seems like Google / Blogger should be thinking about this...
