Rebranding your show is something you can do as a podcaster if your show changes topic a bit, or you just get tired of the name. This podcast was rebranded with this episode. It's not Podcast Quick Hits – By PHD. It will likely just be Podcast Quick Hits soon, but that's what I did here.
I changed the artwork int he feed, and the title of the feed and it took about 8 hours for iTunes to pick up the change. And I'm going to watch the other directories and see how long that took, but I figure in 3 days, everyone will have the change.
