Thank you.
I'm glad I had the chance to finish it up -- I will be leaving tomorrow for a long-anticipated trip. I will have semi-regular email access, so please be in touch (greg[dot]bloom[at]gmail) if you have any comments or ideas, or if you'd like to be put in contact with others who are discussing the best ways to get organized.

Next year, we hope to consolidate this work, along with a set of concrete proposals for improvements to the model, into a web site.
