What would life be like without advertising?

It's hard to imagine a world without advertising, but a new site by the folks at Web dev shop Mindrally asks visitors to do just that. It's a simple app. The site begins the sentence "Without advertising," and users complete the thought. Some early answers suggest that such a place would have better products, companies that make real connections with consumers, and people who make eye contact with each other on the subway. One person said that in such a world, "no one would know anything."
