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.
Many of my friends organize events and have group conversations on Facebook, and I miss out on a fair bit of it. I still have an account, I just don’t use it except to check once a week or so if there’s something happening. I hate it.
