Unfortunately, it is not paranoia. But it's not necessarily the government and its surveillance that is the biggest threat to privacy. Corporate interests collect, aggregate and sell your private information all the time. They know a lot more about you than the IRS or NSA. They are being run by a generation of intellectuals who have little love for freedom and privacy. They were indoctrinated in universities and taught that "wrongthink" is heresy and deserving of punishment. It will not be long before these apparatchiks will be be misusing social media information for political ends.
