This is a honest question. I have two RSS services hosted on my server, and I don't see the point. RSS is by nature distributed, and subscribing to my own server just makes the source of all news being the same. What is the advantage? What do people use it for?
Miniflux is possibly the most important thing I self host. It tells me when software updates (basically everything on GitHub has RSS). It's also great to keep up with blogs that don't update consistently and also stay out of the "there are only three websites" bubble.
