Mackey apologizes

What is it about otherwise sensible, admirable people embarassing themselves with posts to message boards?

I refer, of course, to Whole Foods CEO John Mackey, who now finds himself formally apologizing for his secret life as "Rahodeb."  Surely his credibility has taken at least as much of a hit as John Lott's did — although Mackey didn't go so far as to pose as a member of the opposite sex.  What a shame.
