There are so many products out there that I would love if only I knew about them. I would love to be provided with information about all of these free software alternatives. I would love to know about that new and delicious microwave popcorn. In fact, I would use a browser if it tracked my information, the websites I visit and the e-mails I wrote if it introduced me to products that I wanted to buy. Advertising would not be an annoyance, but a feature the way that it is a feature for those types of people who read the NYTimes Real Estate section, various electronic product magazines or www.fatwallet.com. Perhaps over time, producers could use this information to make even better products for me. Three hundred years ago, such good service could only be obtained through a privately commissioned artisan.
