I think Mayer's a very talented guitarist. I really enjoyed his music when he moved toward the blues. He may never have the social skills to let his sense of discretion override his need for attention when being interviewed, then again, he may learn from his transgressions. You shouldn't talk trash about people you've been intimate with, or, as the old saying goes, "don't kiss and tell".
But to be honest, I like Joe B. more as a blues player, and I would be astounded to read such remarks by Joe in an interview. Mayer, I wasn't that surprised. Go figure.
