For the people that start fearing about Google, I suggest reading the following article: Google goes click.
Among the others, I liked this quote:

Further proof, if any were needed, that Google
isn’t a technology company that makes money from ads, it’s an
advertising company that uses technology to lure eyeballs

I start to believe that Internet Search is too delicate a feature, is so important that it cannot be left in the hands of a monopoly.
Internet Search should be property of no one or real competition and alternatives should be promoted.
