A large number of Self-Styled Collective Intelligence Projects — Citizendium, Digital Universe, DMOZ, Nupedia, Textop, and last alphabetically but far from the least significantly, Wikipedia — have turned out to be, or seem fated to be, major disappointments to those observers and workers who have been dreaming of such things and working to build such things from the day they first touched that Monolith in Olduvai Gorge.
I'm sure you don't need Euclid's algorithm to work out the common denominator of most of those projects, but maybe it would help to tease out a bit more expressly some of the design factors that have led them to, or will most likely lead them to, the despair of all our dreams and work.
