• Here in Germany in my circle (which has people from mid-twenties to 60+, from the North to the center), most people use Signal, with Telegram being a rare outlier. WhatsApp is what everyone uses, though.

      • I’m Australian but living in the USA now, and practically everyone I chat to uses Facebook Messenger after switching from MSN Messenger when it shut down. I’ve got Signal and Telegram installed but barely anyone I know uses them.
