Does not having any social media presence have any negative impact on a person's social life?
Social media presence as in having accounts in your name with you being visible in the profile picture in mainstream sites (Anything Meta, Twitter, Snapchat, Tiktok...). I don't consider anynounmous accounts on Lemmy, Reddit, Kbin relevant to the scope of this question.
Same for me. Keeping in touch with friends is easy enough with my phone and discord. Hasn't affected my dating life in anyway or hindered my ability to meet new people in general either. I'm 34 for reference. I had Facebook when I was much younger but haven't used it in years
