Here on OStatic, we've frequently debated whether fragmentation is good for open source projects, or not so good. We've published posts arguing that centralized management of open source projects and documentation could have big benefits for users, and we've run many posts on successful forks of open source projects.
When the topic of fragmentation comes up, people often gravitate toward arguments surrounding how centralized funding could advance many open source projects, or how centralized marketing efforts could. But what about development? Recently, at the Libre Graphics Meeting in Madrid, the developers of GIMP, MyPaint and many other free graphics applications got together and talked about an important topic: how to work together better.
