Mac fans across the world are eagerly awaiting Steve Jobs keynote at Mac World with bingo cards in hand, but despite all the rumors of the "MacBook Air" and the iTunes video rental store, there is one feature that I wish Steve would announce but that I know will not materialize anytime soon. What I'd like to see from Apple in 2008 is an iTunes marketplace, a place where independent media creators can set their own price for their work and share the profits with Apple.Yes, some independent artists have been able to sell their music in the iTunes store, but there is no means to sell video podcasts or other similar materials through Apple. Back in January, at the Web Video Summit, I listened to Douglas Gayeton explain how Apple was unwilling to market his evocative video series, My Second Life - the video diaries of Molotov Alva; it just didn't fit into Apple's business structure. Fortunately for Gayeton, HBO purchased the project and it may still eventually find its way into the iTunes store. Unfortunately for all of us, the first episode has been removed from the web, and the only copy that remains online has been augmented with subtitles. For years now, I've envisioned a sort of eBay for digital assets. I spent several years trying to parlay the resources needed to build something similar, but I became increasingly frustrated, and eventually put my plans for the Rise Up Network aside; once YouTube became a pop-culture fixture it became even more difficult to convince people that such an endeavor would be viable.
