The default, out of the box setups for Moveable Type and Blogger create files at index.rdf and atom.xml automatically, respectively, correct? Seems like a pretty good reason to look for those files if it's indexing a known weblog that hasn't done the expected autodiscovery mumbo-jumbo in it's
Looking at my logs, though, Google is indexing my RSS 2.0 and RSS 0.91 files, and not my Atom and RSS 1.0 feeds.
Dammit, Google is flexing their muscles and trying to kill Atom and RDF. It's a conspiracy, I tell you!
Stay the curse.
