One major stopping factor for those who produce audio content, and those who have the ability but are hesitating jumping into the game, is that there's no good distribution mechanism. Audible.com is a lovely and niche resource, but they are very selective as to whose content they post, making it difficult for others to put stuff out there.
By creating a chain like this, it gives ordinary people the option to jump on board with a ready-made audience. It's very 'net spirited: giving the finger to "the man".
