Investigators can use your publicly available social media content as part of the security clearance process, though their definition of "private" remains to be seen.

Director of National Intelligence James Clapper yesterday signed Security Executive Agent Directive Five, codifying federal background investigative authority to incorporate publicly-available social-media information in the security clearance process.
The policy does not require security investigations consider social media information. Instead, it permits the collection of publicly-available social-media information if an agency head determines it is an appropriate investigative tool.
Absent a national security concern, or criminal reporting requirement, information pertaining to individuals other than the individual being investigated—even information collected inadvertently—will not be pursued. In addition, investigators may not request—or require—individuals to provide social media passwords, log into a private account or take any action that would disclose non-publicly available social media information.
