To clarify my +1 to "Ship it": At AOL, we are using Atom internally as a data exchange format (and just converted to 1.0 syntax). We are using an early version of the introspection document as well, but only for limited internal use as it's nonstandard and likely to change. When the dust settles on the APP we plan to use it both internally and externally. Thus I have a strong interest in settling the dust.
