Doug Nelson writes "Michael Buffington chose to build a weblog using highly automated content aggregation tools around a single keyword, asbestos, because of the high click through rate associated with the ad. 'The subject matter, while weighty and all that, is of little importance to me. It's not that I don't have opinions on asbestos and asbestos reform, because I do. The whole point of the site is to experiment with an idea. I built a tool that helps me aggregate topical news with the help of Google's Alert system. So far it works wonderfully. But there's a second motive as well. Right now asbestos reform and asbestos related litigation is on fire. Lawyers are paying anywhere from $15-100 per click through on Google ads. The second part of this big experiment is to see if I can capture some of that click through revenue while still providing a somewhat valid service to people who might arrive by search results.'"
