I tried ttrss, freshRSS, miniflux and a couple other hosted solution: all made use of some "modern" feature that prevent me from using it on a ageing BB10 device. So it now host my own instance of rss2email and just get my feeds as email.
I wound up writing my own but mostly because I couldn't be bothered with complex setup: https://github.com/rcxdude/nobsrss . It should work on basically any browser, it uses no javascript. However it's super minimal to my RSS use-case, which is basically just notifications (it doesn't attempt to parse or render the content of the feed beyond the link).
All these projects to self host a copy of google reader are kind of missing the point. A native RSS reader that runs as a single application (ie, not web-crap) does everything better, faster, leaner, and more reliably over long timespans.
I'm all for 'self-hosting'. I do it for all things that require it. But an RSS reader simply doesn't need that kind of complexity. It's cargo-cult.
