Mine hasn't disappeared. Just renamed itself to "CNET.com".
Is anyone else having issues with iTunes and The Real Deal feed. Today I noticed the feed is gone. Tried to re-subscribe nothing, tried to download an individual show started to download then disappeared from the Downloads queue. Has Rafe finally tarnished Tom's good name and is being black balled by Apple. XP did run update XP Security Update for Windows XP KB951748. Not sure if this is the cause.
