it’s not a meme unless it goes viral.
If you want to be pedantic, it’d be good to know that that’s not what a meme is. A meme is a unit of cultural information—analogous to a gene being a unit of genetic information. A meme may not go viral, just like a gene might not be successfully copied onto other generations, but it’s still a meme nonetheless :)
I’m curious: have you ever liked Twitter?
Because i could understand not seeing any downside to leaving a site if one has never actually liked it. But, many people liked (and still like) Twitter. I personally have known many interesting people there, and even started some nice in-person friendships. I don’t like at all what’s become of Twitter; i have it now blocked through the LeechBlock extension so i don’t fall into doom/shit scrolling. But i think there’s still some good in there. I can totally understand how many people would find it difficult to fully leave; myself included.
