Google Base and Atom?
I find this interesting since based on conversations on the atom-protocol list, it is clear that Google is very interested in the Atom API. Perhaps they have already built this Atom store that Adam is arguing for and will expose the Atom API as a way to interact with it. Perhaps this Atom store accessible via Atom feeds and the Atom API is Google Base? Speculation is fun.
My guess is that it’s a safe bet.
