iTunes. Since a lot of people only listen to podcasts through iTunes, this is an issue. So, I've started a tumblr for the podcast. The only problem is, now iTunes is giving me a completely different error message on why it won't take the feedburner feed for the tumblr (and you have to iTunes with Tumblr, in order to make it look pretty.) This error looks like a problem on iTunes end, which hopefully means it will be resolved sometime soon. But still, this is getting old.
