The question here along with most of the answers proposed are flawed... The marketplace needs to be designed in a way that appeals to the largest number of poeple possible. Obviosuly it's not possible to please everyone, but when someone is asked how they would design it, they need to take into acccount that they are not the only person using it. Many hours go into surveying and research before they come up with a proper design. Furthermore, not one single person creates the market. It's dozens of poeple who work together as a team to do so. The team is comprised of not just code monkeys and UI designers, but statistical mathematicians, business gurus, and many others. No one person on this forum has the knowledge or resources to eve begin to say how the market "should" be made. I agree that Google's current version is flawed in some aspects, however it also shines in many others. I am sure the folks at Google are hard at work thinking and researching up new ways to alter the market, but nothing we say or do will influence their decisions at the very least.
