As the others have said, we'd love to be more "open", but we can't really be more open until we've released a release based on blue, as its very hard for the community to understand what we're talking about when they haven't seen anything like blue before. Once we have a release, we'll try to explain what we're changing based on older releases in a blog-like format. We're never going to satsify everyone, but as Bump says, Blue is a turning point in the entire way MTA works and is run, we'll have more information on this in the future.
