Dear Colleagues,
As the discussion on [[Wiki Research Ideas/Research Hub]] has been rather successful, I have begun a general summary on the matter : http://meta.wikimedia.org/wiki/Wiki_Research_Ideas/Summary
It appears that three structures are needed : a Laboratory (cf. Ward Cunningham's suggestions), a Journal of Wiki Studies (focusing on sociology and media studies) and a Journal of Wiki techniques (focusing on computer science publications and giving public exposure to the laboratory's experiments). Such a configuration would solve the disciplinary problem.
Concerning the Journal of Wiki studies it appears we are getting quite near the following step — that is, creating the editorial committee and launching some kind of a recruitement campaign for the scientific committee.
If you are interested in any of these initiative feel free to join the volunteers list : http://meta.wikimedia.org/wiki/Wiki_Research_Ideas/Volunteers
