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.
I don’t think so. It’s just a little more inconvenient.
For example: I don’t need to see posts from friends to know how their day was. Instead, I just call them or meet them for a coffee and ask about their day.
The old fashioned ways still work well.
