people who say it's a dumb idea just relying on adsense.
Been webmastering since '98. And haven't seen *any* thing as remotely effective and rewarding until AdSense for such little effort as putting some silly little code on your pages.
Sure it would be lovely not relying on AdSense completely and instead opening gas stations or McD franchs on busy intersections... but I don't know how! :D
