My Facebook is only memes, only from the large meme pages, not the ones I like that I have to check manually since they'll never end up in my feed. And news articles.
It started with Facebook just hiding what your friends are posting. It still happens that someone shares a photo once a year or so, but I will never get shown it. I just browse my friend's profiles manually.
That was extremely dissatisfying about Facebook. I’d see an endless stream of crap from people that I barely knew and didn’t care about at all, and then when I’d look at a profile of someone I actually knew and did want to keep up with, I’d see posts about significant and interesting things that happened in their lives which Facebook never showed me. I tried to get them to stop showing me irritating posts about politics - unfollow people, block people, mark “show less posts like this”, then it would come up with more political posts from people I didn’t even recognize. Meanwhile, oh, colleague got married…. sure, just never show me that post and show me 15 idiotic political memes instead.
Might as well say Instagram isn't social media either, nor is Facebook or Twitter. Social media is just a platform where one of the biggest parts of it is the commenting system. Its a social media platform for content aggregation. The commenting makes it social.
There are tons of "but Lemmy isn't social media because blah blah blah!!!" comments here by the kids who think they are too cool to be lumped in with the instagram / facebook crowd.
