It's not just that, it's also the style. If you compare the page on "propaganda":
https://systems-place.wikispaces.com/Propaganda (n.b. I moved the source reference to the top of the page because when I started reading it I thought "gosh! This person writes really well!!" and then i realised from the hyperlink at the end that it was actually Noam Chomsky's work!)
to, for example:
http://www.globalissues.org/article/157 ... -the-media okay, the latter is not a wiki, but you can clearly see that the author has used a selection of quotes to provide a more structured analysis rather than a personal "polemic". As a potential co-contributor, it would be much easier for me to add value to the latter.
I'm not saying that the material added is rubbish -- it's actually really good stuff (although sometimes I wonder what the "systems" connection is

), but I think a different style needs to be adopted for wiki contributions.....
