A comment that bears mentioning: it's important to clarify near the end of the introduction why you ordered the sections the way you did. In the response to the reviewers' comments, you indicated in one location that they were alphabetical, but then in another comment you mention that the order is not arbitrary. In yet another location you mention that you consider all topics to be of equal importance. Regardless of the original organizing principle, please explicitly state something near the introduction about the logic behind the existing order. That will clarify some of the issues brought up by reviewers and no doubt by future readers.

In your final submission, please clarify the logic behind the topic ordering.
