@bob @rysiek As I think I've observed before, XMPP seems more like a toolkit to build messaging systems rather than a complete system in and of itself. You seem to need to consider clients and server feature support. I use Wire as an easy-to-setup alternative to Skype, especially for friends who don't have a high technical ability. Hopefully it will federate. Also watching the Matrix space but not sure what they bring to the table. Keybase does its own thing and I'm not sure what new thing it brings to the table either. Too much fragmentation...
