With Facebook doing pushes from HEAD, sites like Flickr and others releasing features day of development. How does a product team with such a huge product iterate? I know D3 is NOT a website and clearly more complex. I'm sure you do, but I do sincerely hope customer trust is part of the process. Trust that we can handle iterations of a product as long as the initial release feels complete. If a "feature" is missing or not ready, we will not be too upset if it is not included in initial rollout.
Keep up the good work!
