If someone was asked, "Would your rather use a website that has ads or one that has no ads?" , they would most likely choose the latter. However, Wikipedia has shown the world something that no one would have expected; it seems as if most people would rather have the ads given the circumstances.
Most people being commenters on HN? Or the 500,000 people who have donated to Wikipedia?
How many of those that donated thought that the advertisements would disappear after they gave money?
