20Google Kritikhttp//www.google-watch.orghttp/
/google.blogspace.com/
- 2003-02-21 (BBC) "The much-praised reputation
mechanism that is supposed to ensure that
bloggers remain true, honest and
factually-correct is, in fact, just the rule of
the mob, where those who shout loudest and get
the most links are taken more seriously. It is
the online equivalent of saying that The Sun
newspaper always tells the truth because four
million people read it, and The Guardian is
intrinsically less trustworthy as it only sells
half a million." - Unsterbliche Cookies
