Do You Tweet?

        This article claims the Library of Congress is archiving every message sent from Twitter's six-year history from spring of 2006 to December 2012 — a total of 170 billion tweets —  and states, “ . . . the struggle now is for the LOC to create a keyword-searchable catalog for the vast amount of metadata associated with the archive, including the time and location that indicate a tie to certain events.”   Is anyone concerned about privacy?
