I find basically all social media sites too confusing to use, starting with when I first attempted to use Facebook around 2010 and couldn't figure out where the hell anything I posted "went" or where anything I saw was "coming from" and couldn't figure out the distinctions between various pages or types of posts. I'm told by a longer-time user buddy that the UI made a lot more sense in the early, .edu days.
I spent years not realizing Instagram posts could have more than one image. Now they have videos, too—are mostly videos, even—which just seems wrong to me.
Twitter confuses the hell out of me. Tiktok is constant frustration, if I try to use it.
I swear, I'm not even that old and was definitely not old when I first encountered a lot of these sites. IDK how they're so successful when I find their UIs totally unusable. Must be a me-problem, I guess. I manage to figure out shit like Paradox Games UIs without too much trouble, and they're regarded as exceptionally dense and hard to learn, so it's not a general problem of mine with all UIs.
