[san-tech][03486] Re: DARPA CLIQR Quest (Cash for Locating and Identifying Quick Response codes (CLIQR) Quest) Challenge

"DARPA Challenge Doesn't Go Viral On Twitter"
 Agency ends two-week QR-related contest--promoted only through
 Twitter, Facebook, and other social networks--without anyone
 finding all 7 posters with special codes.
 March 19, 2012, InformationWeek

  "The Defense Advanced Research Projects Agency (DARPA) recently
   ended its CLIQR challenge without anyone successfully completing
   the contest's full task, giving the agency new insights into
   the effectiveness of social networks versus more traditional
   forms of online communications and media outreach to spread
  "The idea behind the challenge was to get people to respond quickly
   to simulate how citizens might mobilize for aid and relief during
   a time of crisis, according to the challenge's website ..."
  "The key to the challenge was that DARPA did not engage in its
   usual outreach strategy ... Instead, it used Twitter to announce
   the challenge and encouraged participants to use their own social
   networks as well, such as Facebook, to find the posters."
