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.
Looking for work would be tougher. Even when I finally retire I will keep my linkedin just for folks that need a reference or such. Myabe 5 years down the line could dump it.
