The problem with many OS projects is that being distributed leads to isolation. Obviously, OS projects need to accept input worldwide, but they should work more to establish cores in major cities (San Francisco, New York, London) that meet once a month, and have "hackathons", on the weekends. A lot of communication that really can't happen through Git and mailing lists would occur, and the projects would come out a lot better. In-person interaction between developers, as much as is possible, would really help these projects a lot.
