Feed reader (podcast player, basic XMPP client and also Gemini protocol client) which supports RSS/ATOM/JSON and many web-based feed services. - martinrotter/rssguard
It is many things. Basically a way to store some XML documents on the xmpp server and allow subscription to them. It is used for a lot of background stuff in XMPP whenever you want to store some structured data on the server.
What does this allow to do? What’d be a use-case? Does that add something over other feed readers that’d be advantageous?
Basically it allows reading blogs and such made with Movim and similar XMPP based blogging platforms.
Is there any good explanation about what PubSub is and what I can do with it?
I could read the XEPs, of course, but I’d prefer seeing what it can do over finding use-cases by reading specs.
