I like Signal, and I use it... with one other person. No one uses Signal.which is its biggest problem. Without adoption it's a useless app.

Most of my contacts use signal.

For the few that don't I have IRC, email, sms, phone calls...

Never used WhatsApp, Telegram etc

What I am saying: it depends on your individual bubble and where you come from. ;-)
