Pinker is designed to make the world pinker by enabling people to give and receive positive feedback from one another. You simply enter the feedback-selection page at least once a week, choose a trio of feedback messages you want to give someone else, and send them. On the home page, you can view the feedback you’ve received, displayed in a graph as well as along a timeline. In addition, you can search for the feedback received by any user registered in Pinker, encouraging a positive outlook and mutual appreciation among people.
