> Everyone This is not true, at least outside the US. The varieties of service people use to communicate vary much more than this. Line for example, isn't used by a single person I know. Many won't use whatsapp (as a Facebook company). Signal is strange and intimidating to non technical people and so on. > if you don't think it's worth asking, that's probably because they're not your friends at all. I'm specifically talking about good friends, non geeks, I've known for decades. They're comfortable with their platforms of choice. This kind of inflexible - my way or the high way communication style you're advocating, isn't a healthy or effective way of maintaining very long term friendships.
