Andem: Good point. My guess is that since Wiki has all- encompassing content the user actually is more likely to stay within wiki domain clicking around meaning that the back buttom is not used as often and time spent on the wiki domain is significantly higher than say on hubpages. Thus wiki may win in terms of the new row of user generated signals. The system of internal highly contextual links used within wiki is very sound and wiki is HUGE. Both in terms of traffic, PR, contents etc, It is as big as Google itself. This hugeness gives it a special spot in Google. While Hubpages or EZA is a content farm, WIKI is not the farm - it is so to speak super farm. It is like the economic laws that apply to average countries, do not apply to economic superpowers. This is the best analogy I can come up wuth.
