I've caught up on the listings in the MyPodcastCenter.com Podcast Directory. There is nobody waiting to be “approved” at this point – although I'm sure that will change in a few.
My Podcast Center is the only directory (that I know of at least) that has both Podcasts and sites about Podcasting. I designed this site under the guidance of the late Ken Giddens and we developed this thing to help Podcasters (or sites about Podcasting) get the kind of outbound links the search engines like.
If you haven't posted your site there, you can do it at this link.
Please pick the right category when you do. That's what slows me down.
