Sam Ruby has a wiki for discussion of the new Weblog (syndication) roadmap -- a plan to create something like RSS that in vendor-neutral and universally supported.
Because the name is such an emotional instance, a lot of people are just calling it PIE. I like pie, too.
Tinderbox will support the roadmap if it can get any traction. Tinderbox 1.3 already supports the Blogger and Metablog API's, and is designed to make it easy to add additional support. (I don't really understand why the discussion to date has been so heated -- what's an additional Facade pattern among friends? No doubt I'm missing something.)
