I’ve met both the good kind of insane genius that uses it as an IDE and the crazy-board nutjob that uses it as an IDE, but both are decidedly not sane.

‘vimtutor’ is your friend. Nobody sane uses vim as an IDE, but if you have to ssh to a host to fuck with a config file it’s pretty nice to know because you can guarantee that most distros have at least vi, if not vim.
