Yeah, I don't get why the meme is about vim instead of ed. https://www.gnu.org/fun/jokes/ed-msg.html
I've been using Linux as a desktop for over a decade and have never heard of ed before. I'm assuming that its general lack of popularity is why no one talks about it
ed is much older than Linux. I'm surprised you haven't at least heard of it. I found about about it though the old AT&T Unix tapes
