I just answered a question and as per being beaten into submission multiple times in the past by people editing my previous missives, I used back ticks to highlight some text. (See my answer here)
But what was interesting is that someone replied with the comment
It's not enough of a change for me to put an edit through, but code blocks are not for emphasis, and using them as such is detrimental to the Stack Exchange experience, especially for users of assistive technologies like screen readers. The backticks (`) should be replaced with single (') or double (") quotes
I had never considered this before. So what is the consensus on back ticks? What should I be using?
