Reddit is really the only social media I actually interact with on a regular basis and that's largely limited to a few subreddits. I watch videos on YouTube but never read or post comments, I have a LinkedIn account that I forget about until I decide I want to look for a new job, and I have a discord account but it's use is pretty much limited to the server I use for my weekly PF2e game so I'm not sure how much I consider those 3 to be me having an active presence on them.
