A growing number of Ted Cruz supporters are checking their smartphones every day, in an effort to gain points and make their way to the top of the "Cruz's Crew" leaderboard.
Online communities are weird. These points are seemingly worthless to the individuals earning them, beyond the in-group signalling value among "Cruz's Crew." Yet people are willing to trade their friend's (sic) contact information for them.
If this is successful as an information gathering tool, it seems likely many more (and more well polished) versions will be popping up in other campaign apps. What other domains might we see this -- maybe religious or music groups? Does its success mean we shouldn't take seriously the new branch of experimental economics that uses games to make inferences about various economic theories?
