Chris Anderson of The Long Tail Blog has a good post on The Probalist Age and the Wikipedia vs Britannica debate. Chris has also found a way to cheat Google – by using unpopular keywords on his ultra-lame Google Ad, he gets thousands of page impressions but because there are no click-throughs, he doesn’t have to pay. Thats free advertising by having an unattractive ad. Pretty smart. Do Chris a favor – don’t click on his Long Tail Blog ad or it will cost him O.40 cents a click.
