I'm actually not that into actual self-hosting (it feels too close to my day job). But i love the idea of it, and actually do host my own RSS Reader: It's selfoss (PHP + SQLite, so, very simple) and i have been using ever since google reader shut down. It runs on my uberspace.de instance.
Wow, that looks amazing! Will definitely check it out for a side project :)
