Its the nature of the beast. Let's face it, the internet already has everything and more. If you really want to know something all it takes is a search. Even the answer to this question, why is it, is already there. Its not even necessary for me to do a search, because I know its there. Its there on Rennlist (the Porsche enthusiast site) its there on WatchUSeek, and visajourney and countless others.
Its there in Eclesiastes: "there is nothing new under the sun."
