Unfogged makes fun of Matt Yglesias’ spelling.
I used to have the opposite problem as a teenager: I read constantly but I had no idea how most of the words I was reading were actually pronounced, since they weren’t often said around me. But I kept wanting to use the words to see whether I understood them. An-hillee-eight-ed, knave for “naive”, and so on. I still occasionally drop into an obsfuscating mumble if I’m using a word that I haven’t heard pronounced that often, or a name that I’m deeply concerned I don’t know how to say properly. Old habit.
