@vv4rner While I love what RSS enables and there’s a huge ecosystem for it, I am against it for DRY reasons. It’s stable in the fact that no one has iterated on it in over a decade. It also helps that WordPress core handles a lot of the admin tax for me on maintaining it, but it has caused metacrap issues for me in the past.
So what to do to replace RSS? If you look at most of my content, I’ve got the HTML marked up with (richer) microformats for those who’d like to consume that directly without needing a side file for it. There’s an existing ecosystem of microformats parsers and even social readers that use microformats over RSS. Incidentally microformats are also part of the semantic layer that makes site-to-site converstions on IndieWeb-based sites work better.
