Clinamen

Certainly, yes. Citizendium is a commons, but it's a different kind of commons - one that bleeds into the realm of "property." That is, while Citizendium does not allow any one person to determine ownership, it does deal with property differently. The move to attach particular writings to particular people treats intellectual property differently. This isn't wrong, it's just different. I would say the same about Wikipedia. Their choice to allow anonymous edits isn't necessarily wrong (There are certainly problems with such a policy, but it has also allowed the the text to become what it is.)

The chapter is very much in the early stages, but if there's a continuum with "property" on one side and "commons" on the other - I would (and will) argue that Wikipedia and Citizendium are at different points on that continuum.
