Yves is a valued first follower in the agile community. He picks up the bleeding edge ideas, experiments with them, and passes on what he learns via his blog, conference sessions, Twitter and more. For example, I’m not sure who first came up with pair coaching, but I first learned about it from Yves, and thanks to his work I’ve been able to apply the techniques myself.
Yves is always at the front of new movements to spread new ideas and build community.
