Developers are motivated by points and games even if the points mean nothing. The document proposes gamifying code reviews by giving points to developers for the number of comments they leave on pull requests. After implementing this at one company, they saw a 170% increase in comments and 200% more reviewers, with typical months now seeing 80 reviewers and 2300 comments. The system also encourages friendly abuse and trash talk between developers.
