Turn Off "Ping"

Here's a suggestion from Jim Hamm.  "If you have no interest in participating in the music social network "Ping" (which I don't) in iTunes '10, here is an article on how to turn it off (which I did)."
     Questioning Jim about his opinion of changes in iTunes '10 he informs us, "It seems fine to use, with slight differences than the prior version."  Macworld describes the changes here.
