Q: My New podcast is not coming up in iTunes when searching for it.

Here you go:

(Despite the fact that only two episodes appear in the Search results, all four appear in the iTunes Store.)

iTunes no longer uses a keywords tag - you don't have one in your feed: it never worked properly anyway.

There appeared to be some bugs with iTunes Store search earlier today (at least, for podcasts, anyway). It looks like things are clearing up now and it's getting back to normal.
