This is great idea, but where is the open source version? I want the professor of art history's guide to the National Portrait Gellery not some anonymous nasal american tourist voice. I want Sister Wendy's homebrew podcast and I want a web site that aggregates all those user generated podguides - did I invent a new word for the genre, did I? er, no. A trip to the $29 million dollar search bar - see below - and I find http://www.podguides.net/. Now this looks more like it! Unfortunately it doesn't seem to have exactly set the world alight. Hmm. I still like the idea, though. Needs a bit of marketing push I guess. Its definitely a web 2.0 kind of business and imagine all the advertising you could sell.
