I use RSS daily, but I am very much anomaly among my friends. For most people I know RSS just withered and died and got replaced by Facebook or whatever asocial media they are on. I ended up rolling my own server (in scheme using sxml) and writing some minimal clients for it (tui, Emacs and web). It is running on a raspberry pi 2 and is currently using about 5mb of memory (the guile runtime is a large chunk of that)…
Sure, yeah, using RSS is rare, but it always was, and nothing was going to keep the vast majority of people from using Facebook and Twitter instead. I don't understand why you rolled your own server. Feedly works great. If you did it because it's a fun project, that's awesome! But it certainly isn't necessary if your goal is just to subscribe to RSS feeds.
So I rolled my own. I will probably port it to use SQL so I can do easy searching when my kids move out :)
