Currently, I, my entire Family and everyone I know use Signal. And everyone that doesn’t want to can contact me via Matrix or XMPP, which literally no one ever does, even thought I know a lot of IT and CS people, but I keep them as options just to offer them to people.

I mean, there is also phone, SMS and email of course, but people seem to prefer a new messenger over actually contacting me in any of these ways. And then I’m always like “look, you can choose one of countless ways to contact me, if you like none of them, that’s a you-problem”.
