Oh, I'm quite aware :). It's an effort of extreme dogfooding of https://github.com/khan/perseus https://github.com/khan/perseus. This post doesn't use anything interesting, but if I wanted to post about some of the interactive math content we're doing there, I could actually embed it. It is also useful to learn how annoying it is to embed (answer: much more annoying than I'd like).
