I want this to take off. I'm tired of having to follow trends because people suddenly think there's a new shinyshinytrendy thing around: IRC to ICQ to MSN to Skype to Google Talk to Facebook Messenger to Whatsapp to Signal.
Pidgin is good (I also miss the ancient Trillian, even though it was closed source), but limited to a local device.
EDIT: for encryption fans, I've been wondering for a long time now: why would you trust ANY 3rd party with your so sensitive data instead of running your own service? Are you not aware of OMEMO for XMPP? (See https://omemo.top/ )

There are XMPP Transports as well for these (see https://git.eta.st/eta/whatsxmpp , https://gitlab.com/nicocool84/spectrum2_signald , but sadly https://spectrum.im/ is surprisingly finicky to set up.)
