-After talking to a lot of techies, we've found that most believe Postgres is the best (operational) database but they *still* choose other databases. This is overwhelmingly because "the other one was quicker/easier". Our goal is to make it quick and simple to get started with Postgres, so that we never hear that excuse again.
