The only other directories I know and have used also are:
http://www.podcastalley.com/http://www.methings.com/podcasts/http://podcast.com/http://www.podbean.com/podcastshttp://www.spokenword.org/I think that No Agenda maybe on that slow slide down; donations were off a bit; and maybe the business plan is hitting snags. It was a different podcast when Adam would talk about No music, no jingles, no Ads, No Agenda. I still love the show; mainly and always because of John; the sensualist and hedonist; and one of the better storytellers in media. The only man that can truly ground Leo Laporte to reality when he gets a little too elite.
I hope the other links are helpful, I'll try to think of other things; I do have time for that; just wish it was a money maker; the thinking thing that is. Right now I am trying to track down some Warner Bros. Cartoons; it is going to be a long road to collect copies of 1069 seven minute cartoons that span from 1930 to 1969; but I already have a couple of hundred; and hopefully I will find a means to get more. Bring on the Torrents; until the RIAA and MPAA take it away. When a person doesn't work anymore; they start collecting even more than before.
It is better to work and be useful;it keeps your mind from thinking too much lol.
Have a good night Austin -Noel
