Perhaps RSS makes a comeback in some shape or form, as a way for LLMs/agents to fetch the latest content from sites?
I just a month ago started moving all my feeds to a self-hosted FreshRSS installation. It lets me create feeds from pages without RSS using XPath[0] or CSS selectors to pick the elements.
I also did a handful of Go applications that generate and/or modify existing feeds to be actually usable instead of just the title. I run those from cron daily and add the generated feeds to FreshRSS
And with FreshRSS I can filter out the "XXX (YC xx) is hiring" posts from HN feeds automatically :)
