Format Wars, Episode 3
I think it's funny when people say that feed formats are really irrelevant because all of the readers support all of the formats anyway. While that happens to be mostly true right now, the new, non-backwards compatible Atom Format spec is going to be released one of these days, and we'll be right back to the chicken-and-egg problem of publishers not wanting to convert their feed to the new version until it's widely supported in the readers, and the feed readers having to prioritize adding support for the new format and managing a release.
I think SmartFeed is going to be a big help in helping publishers manage that transition. When the spec is released, we'll make sure that SmartFeed "down converts" the new spec to the existing 0.3 spec for readers that haven't been upgraded yet.
What's in store for Format Wars, Episode 4 you think? I'm thinking it's going to be in reconciling different namespace extensions for rich media types. Different music namespaces, photo namespaces, video namespaces ... and how about enclosures vs. Y! RSS Media extension for the next generation of podcasting? All coming soon.
