Watching python attempt a transition will be instructive. I recognize that if we had the luxury to start over today many of the projects cultures would perform better. The do's and don't list for starting a project at this point has some traction as a meme. I'm not as concerned about new projects moving forward. But I am concerned that we don't know the do's and don'ts yet on how to transition smoothly for projects that are established.
It's a lot easier to drive a car to where you want to go..if you know where you are. I think a lot of projects know where they want to go..I don't think they know where they are...and they are just starting to figure out its okay to ask for directions. Cultural inertia is a hard problem and we can make just as many wrong turns changing cultures trying to get to where we want to go..as we can deciding on a culture at the beginning.
