All that data is logged and sent back to Digital Green, which use it to populate the profile pages of Farmerbook. Gandhi says: "We plot these farmers on a Google map, and you can jump into each individual village and see all these farmers we work with -- which videos that this woman in this village has seen over the course of time." An orange symbol means she gave a thumbs up to a video she saw, whereas red means she asked a question (in the example that Gandhi showed us, a farmer had asked whether there was a chemical that could be used to combat a kind of caterpillar infestations). Facilitators go to check up on those farmers who say they've adopted the "non-negotiable" parts of the techniques they've seen in the videos, to make sure that they're telling the truth.
