I’m not clear on the difference between atom and RSS. Atom seemed to be the better spec, but for my Astro blog I ended up sticking to the built in `rss` helper it ships with.
Nothing is killed. It still exists, it's an open protocol after all. And I choose to use it, it's pretty fun to calmly follow around 2000 feeds from - mostly - blogs from HN. And cars... I need my car blogs.
Agreed. That nowadays people or even big companies find it outside their core competency to host their blog, have atom/RSS feeds is not because big tech killing it.
