People. Nobody using it. My mom is not on it. What the point?
All my programmer / enterpreneural friends are on Signal / Telegram. All business communication is there.
Ditto, I was pleasantly surprised to see a huge number of people at work / industry acquaintances already on it when I switched it to my default SMS app. I love how SMS/Signal are seamlessly together in one app if you choose to combine them.
Signal requires a mobile phone number. The iPhone app isn't bad, but it's buggier than Messages and doesn't rotate. The desktop app has the usual Electron problems.
