I don't understand why everyone has to come up with analogies about what kickstarter is or isn't. Are people not sharp enough to understand the nuances of crowdfunding sites without simplistic analogies?
The closest and most correct analogy is a store.
now you are making an analogy, you dont understand yourself...
Thanks for telling us what an analogy is, professor, but you missed the point.
The point is that IF people wish to use analogies to contextualize KS, then the best analogy is a shop where one is pre-ordering. An offer is made by the creator, and the pledge indicates acceptance. Even KS's wording is carefully chosen... pledge != donation, and reward != gift.
