How does this square with "mob mentality?" I wonder what the negative side effects of programming in a group might be. Maybe the group is more liable to jump on the first answer to a big problem rather than think it through carefully to find the best answer. Maybe some team members actually perform better on their own, or maybe it depends on the tasks at hand and the experience profiles of those involved. Also, I'm still skeptical that it makes sense in terms of code quality and velocity to have 6 people work on one feature rather than 3 pairs working on 3 features and syncing up every morning. (That's what I did in the past, we had a "tech time" every morning for a half hour or more where we'd walk through code, do reviews, and make decisions as a team.)
