Silicon Valley finding Washington regulators uncomfortably close

The message Federal Trade Commission Chairman Jon Leibowitz delivered this week: Google and other big tech firms may operate thousands of miles from the nation's capital but they're not beyond the reach of federal regulators. Silicon Valley likes to hold itself out as a paragon of corporate virtue, but increasingly federal and state authorities are not buying the "don't be evil" slogan. Unlike oil or pharmaceutical companies that have to work hard to gloss their public image, Silicon Valley — filled with energetic young entrepreneurs building the next generation of gadgets and apps — is celebrated for driving the U.S. economy in tough economic times. But that high shine occasionally gets tinged.
