Google about to print $2.1 billion

Google has announced their plans to sell 5.3 million additional shares that will put an extra $2.1 billion dollars into their pocket.  What could they need this money for?  Google says it's mainly to keep up with demand after their inclusion into S & P.

Others say the funds could be used for acquisitions -- one possibility is "face book" according to Rob Hof at Business Week.
