Just my 2 cents: I am undecided about this. It seems this might be a good idea, but I can see it twisted really quick in all sorts of ways. I am not going to say which, so as not to give ideas to some :-). I think if you make it an exploratory learning experience, in the spirit of cMOOCs, with a community experimenting with and reflecting upon the ways in which knowledge is created in a certain field, the language and processes of that field, the practices of experts, etc. this has great potential. If it is to be a MOOC of the x kind, based on content / resources only, than there are already alternatives, which some have talked about in the comments, that can do the job.
