I don’t know when they started, but Flickr provides photo feeds in both RSS 2.0 and Atom! Hurrah! Maybe I should splice my own feeds together after all?
The problem is I now have various elements of me with feeds: my blog (Atom feed), what I’m listening to (RSS 1.0 feed), my bookmarks (RSS 1.0 feed) and my photos (RSS 2.0 or Atom feed). So if I want to splice, which way do I go? Do I convert everything to Atom? What benefits would I, as a publisher, have if I did that? Or should I convert it all to RSS 1.0? In theory that would mean I could do “interesting” things with my RDF data, but what could I actually do?
My biggest target at the moment is providing comment feeds for my posts. If I publish RSS 1.0 or 2.0 I can use the wfw:commentRss to provid a feed for post comments easily enough (Phil Ringnalda is probably the best known blogger who does this well, just look at his RSS feed, although it seems very RSS 2.0 and very non-RDF), but what about Atom? Sam Ruby currently posts a feeds per-post which include comments but there’s no differentiation between his original post and the following comments in both his RSS feed for a post (example) and the Atom feed for a post (example). Rubbish.
