I just ran into a perfect use case where the <podcast:guid> just fixes the problem in a way that nothing else does. I should probably write that up into a blog post and begin some broader explanation of why <podcast:guid> is so important.
@dave podcast:guid simply fixes podcasting. There is no way to code an app without bugs that catalogs items without having a way to distinguish and identify every instance of such items. If only it could be made mandatory…

I can see a Podcasting 2.0 STORE EMPIRE now... full of t-shirts that say:

"GUID is my Co-Pilot"
"You just got to stick it in there!"
"Podcasting is Audio Only"
"Meat Shake Equializer"

and of course...
"Money Printer Go Brrrrrr!!"
