are you being sarcastic? Its nothing like the power button. Everyone has to press the power button but not everyone has to use Vi.

:wq is one of the most insane key combinations to quit an app and this is just hipster shit where people who use vim think they're the only "real engineers". It's just a disgusting level of arrogance and masturbation. The code is what matters, not the IDE. To focus on it as a sign of technical excellence makes a mockery of what engineers are supposed to care about (comp sci things) and replaces them with all the elegance of a high school bully belittling some other kid for not wearing Nikes.
