It’s supposed to be a listener interface as well, combined with a community effort and a podcast directory.
It looks quite nice, and at least the directory stuff and integration with the Podsafe Music Network is cool. Unfortunately, I can’t get the listener interface working for me. The concept in itself looks pretty twisted, and the operations just don’t work for me. I have no idea how it is supposed to work with iTunes/iPod, and I can’t get *any* podcast to play from the site. This may be a problem with Firefox and/or popups, but I’m not willing to switch browsers to use the site.
I’ll be keeping an eye on it, though – this may have potential; I’m sure it’s just birthing pains.
