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.
