I know of at least two people who will be interested in this site: AmigoFish
In their own words:
a way of finding podcasts and videoblogs of interest to you.
I haven’t created an account for myself yet, or really done much more that just give it a cursory look, but I ran across a reference to it via an entry on a geographic BlogNeighbor’s site while doing research for something at work. It was sort of weird realizing that I recognized some things in his flickr stream just a bit too well.
