Good diagram comparing the process involved in collaboration using wiki and collabopration using email (guess which one is easier!). I would add that collaboartion using Google Docs (which I have some people here at NRC testing today - yay!) works the same as the wiki picture. One quibble with this post: why is there some sort of U.S. Military logo representing the 'wiki' option? I think it would be more appropriate to use a MediaWiki logo, or something similar.
