Thanks Fab for pointing me on this NYT article: Loosing Google's lock on the past. It's about the huge fingerprint people leave on the web: everything can be found on google:

Marissa Mayer, director of consumer Web products for Google, said that people call and e-mail the company regularly to request that links to their names be removed, though she would not estimate how many. Web masters who want to remove their own content from cyberspace are directed to Google, where they can learn how. But people like me, who do not own the offending material, must contact a Web master directly.

I like this statement:

RATHER than trying to have uncharitable comments and images removed from the Web, Mr. Weber said, people should go with the flow of the Internet. "Go in and be part of the community," he said, "and share and be transparent and be open." (...) The most effective way to define and control your digital persona is to start a blog or put up a home page.

"Web logs come up very high in a Google search," Mr. Palfrey of Harvard said. "By creating a personal Web page, particularly one that has lots of links to lots of sources, you can create a gateway to your online identity." (...) "The Internet is a very good analogy to a company," Mr. Dash said. "There is always going to be somebody complaining. At least the first voice they hear is yours. (...) THEREFORE, the secret to burying unflattering Web details about yourself is to create a preferred version of the facts on a home page or a blog of your own, then devise a strategy to get high-ranking Web sites to link to you. Many people assume that a Google ranking has something to do with Web traffic, but that is incorrect, as is the notion that the more links a site has, the higher its PageRank.
