This is actually brilliant in terms of getting applicants. As someone who just started professional development work in 2012, I get sick of reading job descriptions that ask for a candidate who is perfect at what they do, or try to attract applicants with insincere language. The honesty in this posting is refreshing, and while I'm not looking right now, I think they'll actually get some pretty great candidates this way (who might not have the highest self-confidence).
As an emacs user, I find this post incredibly offensive.
I thought the title was pretty funny - definitely grabbed my attention. Good luck!
One thing that caught my eye: Emacs users don't need to apply. While I'm not one myself I'd like to know what's the reasoning there. Did they manage to ge entrenched in vim?
This is an excellent approach. Extremely few people can be the bestest of the best, but luckily only extremely few companies actually need them. Cutting the bullshit is good for everyone.
