News updates all day from your Fast Company editors. The Federal Trade Commission has approached both Google and Twitter concerning Facebook 's $1 billion deal to purchase social photo-sharer company Instagram. According to a source speaking to Reuters, it's not known exactly what details the FTC is curious about, but it was rumored that both these other companies and possibly others were interested in bidding for Instagram--itself growing at a swift rate and thus rapidly increasing in value--which caused Facebook's CEO to move very swiftly and conclude the deal in private without his board's full knowledge

Google, Facebook, and others have made consumers particularly sensitive about their privacy online. That means you need to be sensitive about it too. Big tech companies are no strangers to privacy problems

General Motors's subsidiary, OnStar, is now the one getting tracked by some Congressional leaders after a controversial e-mail it sent out to customers earlier this month.

Last year, Google launched Buzz , a social network "built right into Gmail, so you don't have to peck out an entirely new set of friends from scratch," boasted the search giant. "Buzz brings this network to the surface by automatically setting you up to follow the people you email and chat with the most…[and] building an easy-to-use sharing experience that richly integrates photos, videos and links, and makes it easy to share publicly or privately." Much to Google's dismay, Buzz turned out to be a huge bust, and not only because it was incredibly unpopular among users. The social network was riddled with privacy concerns, so much so that the Federal Trade Commission charged the company with using "deceptive tactics" and violating "its own privacy promises to consumers." Today, Google settled with the FTC.
