Vivek Kundra, Obama's newly-appointed CIO, is the man in charge of developing and deploying IT to improve government operations. He's also a fan of building government intranets based around Google web apps.
In his time as Washington D.C.'s CTO, Kundra used Google's web apps to not only develop intranets, but also content production systems. And according to cnet, he believes in a platform-independent, open source method of software development. Kundra is also a big proponent of transparency and the offering of information online, helping to shape the U.S. Government's updated tech policy.
