I don’t believe in hazing. I am paying them to learn something that I believe will make them more productive for my business in the long run and likely help them in their career when they leave as well. They can still use their favorite other editor if they want, but they should be able to teach vim and emacs to the new programmers I hire after them. Also if they can’t learn emacs, I have less faith they can learn other useful things also when needed.
