I find myself never actually using social media. Good friends belong to the same Signal group chats. I have several of these which consists of cliques I have built up over the years in school and at work and that's how I stay in touch. For those that are further out of reach there is email and linkedin if I really need to dig someone up from the past.
Any advice how to get your friends to switch, when they do not care much about their privacy and have a defeatism attitude with regard to guarding their privacy or simply do not understand, that their actions affect their friends?
