I’m going though the archive of the iProcrastinate podcat (http://iprocrastinate.libsyn.com/) and in a 2013 episode Beeminder is mentioned as a gamification strategy that includes both prizes when one achieves personal goals and losses when one doesnt (the second part handled by Beeminder). The whole episode is quite interesting, the mention is after 55’ , direct link to the episode is here

Perhaps Beeminder should expand to the first part of the strategy as well in some manner
