I hate writing like this. Even if most people don't know the thing you're referring to, basically telling the entire browsing population of the internet "we're all stupid and here's why" immediately leaves a bad taste, particularly for people -- you know, like teachers -- who do know what teachers do, or people who didn't make the assumption being assumed in the first place (which says a lot more about the author than anything else). Pedantic? Maybe. But to me this is a really childish way to make a point that could be better stated in a way that doesn't instantly, baselessly denigrate the reader, particularly when you're writing for a publication that banks on its credibility and reputation.
