Indeed it is true that more people can "write" Klingon than speak it (which I noticed again at the qepHom).

 

But actually, in the first place, Klingon was never intended as a written language, but really only to be spoken - that is: on screen. This is obvious in the strange kind of writing, and also sometimes visible in situations where people ask whether a noun-noun word is written with or without space. When speaking the language there is no difference anyway, so Okrand never focused on that. At least not in earlier years, see the recent note on "wab(_)Do".
