In the age of git and hg, why is a fork such a big deal? Code can still flow fluidly between multiple forks of a project with almost no friction. Some amount of forking is probably healthy in the long run, allowing a different part of the community to take the lead and head in their own direction.<p>In the extreme, if everyone works on an independent fork, and never merges, we lose the benefits of building "team-sized" projects. But that does not seem what is happening here.
