I'm in the "been working with Linux since the 90s" gang so I call vim vi and nano pico and when I started there was a coolness factor to be considered. I was incredibly uncool so I used whatever I wanted, including pico - I mean you used pine for email back in the day and the interface was nearly identical, so whatever.

But I did want to be at least a tiny bit cooler, so I learned vi in a fairly rudimentary fashion. I can edit, jump, delete, search, replace, copy and paste - oh, and I can exit. I've spent so much time using vi, that my brain doesn't even have to think about exiting, not even whether I want to write or not. It just happens like second nature. It's actually gotten to where nano seems unduly burdensome to me.

But really, I prefer an IDE for programming. CLI editors will always be for configuration files and shell scripts to me.
