The first few weeks are filled with things like "Why is (d)elete cut?! I want to delete it, not put it in the buffer! And why do I have to push 'd' twice? This is stupid." or "Who thinks (w)rite makes more sense than (s)ave?"
But then over time, I started internalizing the commands and whenever someone else would echo the same complaints back to me, I'd usually find myself responding "Well, vim is pretty old, so you have to forgive it for not being up on modern terminology. If you just remember the keywords, it usually helps a bit. Plus a good configuration makes it a lot easier to use!"
Now I'm at a point where I find myself hitting ":wq" more often than not regardless of whether I'm actually in vim... and I started looking up ways to use vim keybindings in Sublime Text.
