Good points. My biggest quip with Russian is when "е" (yeh) is written when it is actually the "ё" (yo) character. My second is the "г" character being pronounced as "в" when surrounded by "о"s. And I often make mistakes on how "о" is accented. I wish they would just use "а" when о is pronounced that way. Other than that, modern Russian writing is very sane. I honestly make more mistakes in English due to it's inadequate writing system, and thats my native language. Go figure.
