From the list of “things I thought I’d never see”, Karl Pearson-Cater (he and I were colleagues about a decade ago) posted a great job listing at MinnPost, which lists the following requirement:

• You know the difference between an “em-dash” and an “en-dash” and you know a little about “Anil Dash”

In case you’re interested in the job, here’s the Wikipedia page on dashes and here’s my about page. Good luck, aspiring web editors!
