Like all collaborative work projects I've been following (mostly open-source software projects), this project is eventually going to need more than a bunch of people doing things.
I propose that CWBP2 should be split into sub-projects each and every one of them having a project group (and possibly a project lead).
Possible project groups could be:
-Global Cartography Group (GCG; responsible for creating the overall world map, projections etc.)
-Global World-Building Group (GWBG; responsible for creating the general setting, planet tilting, seasons, moons, climates, ocean currents, metaphysical aspects etc)
-Cultures and Civilizations Group (CCG; responsible for the creation of the general guidelines on what cultures and civilizations exists now and have existed before)
-Fauna & Flora Group (FFG; responsible for finalizing what the biology of the world's creatures, animals and plants is like now and has been before and why)
-Technology and Magic Group (TMG; responsible for the creation of the metaphysics, possible magic and technological achievements both globally and culture-dependently and also deciding the history of magic and technology)
-Deity Group (DG; responsible for the creation of belief systems both globally and culture-dependently and whether or not the systems are based on actual realities)
-Low-Level Groups (LLGs; responsible for adapting the cultures and civilizations into the world based on history, legend, geography and whatnot - this would be the creation of actual locales, kingdoms, characters etc and could possibly be further divided)
-Story Group (SG; people interested in creating both adventure stubs and / or stories taking place in this world)
-Licensing Group (LG; responsible for deciding project-wide overall content licensing cascading into sub-projects and creating guidelines for sub-project participants; this needs to be done in order to avoid a complete mess afterwards)
Persons could then decide on what aspects of the CWBP they find most interesting and participate on that or those.
I don't think an unorganized project is really going to work.
However, this would require some technical alterations like sub-forums.
Thoughts?
