There's a Billy Joel slam on Slate (via 3Quarksdaily) titled "The awfulness of Billy Joel, explained". I am not entirely sure if the Slate piece is intended as music criticism or just a parody of music criticism.
Also on 3QuarksDaily, a commenter has posted a link to a "conversation" between a blogger and Billy Joel himself. Basically, the blogger trashed Billy Joel for indulging in vocal trickery during a performance of the national anthem. Billy Joel responded with a "fuck you". Read the post and the comments by Billy Joel.
