As someone who has generally thought of Vim as the most pathological creation of computer-land ever, there isn't anything in this site that seems aimed to change that impression or even communicate what vi/vim is.
Moreover, I suspect the majority of computer users feel a similar an antagonism to vi/vim and so anyone who's talking about an introduction to vim ought to, uh, explain it.
Moreover, I am a full-time Linux user and I have actually used vi to accomplish small tasks. I can't imagine someone in the know getting anything from this site.
