The one non-obvious thing that I use RSS for is to monitor releases on GitHub, so that when I’m waiting for some project to release some bugfix it gets conveniently listed in my RSS reader.

I used to have it get a digest of reddit posts from my subscribed subreddits, so that I could still get the stuff not posted elsewhere, without actually going to reddit.

I glance at The War Zone occasionally (twz.com) to see if there’s anything interesting and worth posting here.

I mostly use it to digest news, webcomics, and free video games.

My best strategy has been to use Lemmy, and then if I liked a post shared here, I would check if that post came from a site with an RSS feed.

I’ve also been reading posts on bubbles.town and finding lots of fun niche little blogs to subscribe to. Bubbles has its own RSS feeds, too, sharing the highest-voted posts.

Also, more relevant to this community, I’m watching feeds for releases for most of the software I’m running.

I’ve had FreshRSS archiving pretty much all the news sources I can find for the last several years. I use it as my primary news feed, but the archiving is my primary goal.
