very interesting article here..

"•Google has long claimed to be neutral. Their corporate philosophy statement claims: "We never manipulate rankings to put our partners higher in our search results and no one can buy better PageRank. Our users trust our objectivity and no short-term gain could ever justify breaching that trust."
•As the world-leading corporate proponent of an industrial policy to mandate net neutrality for all its potential broadband competitors in cloud computing, and as the beneficiary of "The Google Loophole" in the FCC's proposed open Internet regulations (para 104), it is fair to stress test whether Google's claim of a "neutral' identity is true or just cleverly-executed PR.
