On threadless and sharing ideas (required 1)

I have never personally used a site that shares individuals ideas for retail purposes. Although this is the case, I am in no way saying that it is a bad idea. I looked around threadless.com and believe that the concept the site uses of individuals posting their shirt concepts and getting the credit for the shirt is a great idea; it allows people to get their ideas out there and express themselves.
Also, the concept that the viewers and potential buyers get to rate potential shirts that threadless will produce is a great idea. This idea makes sites like threadless essentially "by the people for the people", in that if the potential buyers find something desireable, the likelyhood of it being available for purchase is greatly increased.
Not only is crowdsourcing a great way to involve potential customers in the selection process, it also is a great money making scheme. The crowd decides what items are best, and therefore is most pleased with the selection and is most likely to purchase from that site.
I think if big market companies used crowdsourcing as a way to gauge how well items are selling in their store, the store would have a much higher margin of profit because they would be able to adjust to what the customers think instead of just arbitrarily deciding when to sell certain items.
