Excellent set of questions
Thanks for that and I appreciate the time you've taken to upload your thoughts. There are certainly valuable lessons for our WikiEd community from the OCWC experience.
An aside - Threaded discussion is not the ideal vehicle for complex discussions where most posts include many dimensions.
However, we're a passionate and committed bunch and prepared to wade through these tomes in the interests of our community. Transparency and a full record of our interactions is more important than usability at this point <smile>. Liquid Threads (the discussion engine in this Wiki) has a feature where after 14 days the community is invited to write a summary. This will help with navigating the discussion.
