I read Mr. Fried's posts. Yes, they could benefit from editing. Most posts I read here could (including mine; if only I hadn't divorced my copy editor wife! Hahaha).

Gently encouraging him to improve his style because his message is valued is not out of line, although I would do it offline myself (which may have occurred). As Eric observed, even (especially) famous authors have editors, badly needed in many cases.
