It may be time to throw in the towel on Atom. Why do I say that? Well, Google (by way of Blogger) has rolled out Atom 0.3 - as have a number of other people. 0.3 is permanent now, no matter what the IETF does with Atom. It's more than that though - if you subscribe to the Atom mailing list, you'll get to see just how little it takes to generate a useless discussion. Take the argument over dates (please!). It looks to me like it will take years for a putative 1.0 spec to come out - and at that point, no one will care. Atom 0.3 or RSS (either 1.0 or 2.0) will have been chosen as the default syndication format by every organization that cares. What value will they see in pushing out a new format? Initially, no aggregators will support it, and some never will (most of the authors will do what I plan to do - take a "wait and see" attitude). The syndication problem will already be solved for places that use it - spending time and resources on making no value changes just won't look that attractive. My advice - admit defeat and move on to something worthwhile.
