Thank you all for your feedback. I've incorporated a number of them and updated the report. It's now publicly available to share with folks who are interested.

@Samuel and the group of people talking about how to re-design wikipedia.  I don't have a stake in the discussion because I just don't know enough of the backstory on these discussions.  But, I do have some hopes about it. I hope the results highlight the importance of taking the kinds of bold action you're suggesting.  And, I hope this is the evidence you need for a real conversation about seriously addressing questions of openness and access.

Thank you for all of your comments!
