Eric: I'm afraid this isn't unusual. The process requires human intervention, and if there are a large number of podcasts being submitted at the time you get stuck in the queue. It's just a question of waiting.
othersal: this is unuually long, but there's little you can do about it. Are you sure the response hasn't got spam-trapped? - try searching on the title of your podcast in the Store occasionally to see whether in fact it has got in.
Thanks for the response. It wouldn't bother me so much if I had some sort of email regarding a wait time or an estimation of when it would be reviewed or some kind of communication. Meanwhile I'll have at least 5 episodes posted on my own site and everyone I talk to hasn't listened because it's not on iTunes yet....so frustrating
