As an RSS user since the early days, there’s something I never get: why is this something that people are hosting? Are you really all consuming so much news, so much of the time, that you need to do it simultaneously on two devices? That sounds like news overload to me but what do I know.
Personally, I catch up once a day for an hour (or two). Seem more than enough and means I only ever need an RSS client. Right now: the Feedbro add-on in Firefox desktop.
As for tips and tools, RSSBox is a useful one. IMO if RSS were more popular this is the sort of thing that would be built into the client.
OK. Given that self-hosters are maintaining two PCs already, I suppose that’s fair.
