Gabriel Scherer set up a research blog for the Gallium project-team, to highlight small chunks of work of the team members in an informal and popularized style. For example, Valentin Robert, Thomas Braibant and Jacques-Henri Jourdan described various aspects of their interaction with the Coq proof assistant, some of which eventually resulted in small improvements integrated by the Coq development team. Articles are published approximately once a week, and the blog gets on average 500 visits a day.
