Recently, I recommended to a friend that basic vim/vi is worth learning because it’s a baseline that you can always trust will be there across different Linux systems.
They asked me what I used most on my home system, and the answer was emacs, but I was very clear that I was not recommending it. It’s a particular kind of person who finds themselves at home in emacs, and for everyone besides those people, selling them on emacs would feel like persuading them to do hard drugs.
I find myself commenting far more often than I did on Reddit. I remember once that I lamented that Lemmy doesn’t have a “super upvote” in the way that Reddit gold used to be (which is a silly thought, given that I have never, and would never pay money to gild a comment). However, I realised that on this more discussion based platform, a short but meaningful comment can readily function as a super upvote. I think the lack of karma accrual for comments/posts also promotes this.
