Hopefully this is a fit for this community (for getting value out of a self-hosted RSS aggregator/reader).
I’m looking for a list of high-value feeds to subscribe to or some alternative ideas to use RSS for in $current_year such as subscribing to a youtube channel without being logged in/directly using the frontend.
Apart from the other things people mentioned here, I recently deployed pinchflat-ngx: it subscribes to youtube channels and produces an RSS feed of videos it downloaded. I had issues with the using the RSS feed from youtube directly - it appears to break more often than not. That pinchflat feed I use in my miniflux instance.
