"Even assuming administrators are completely objective in their decisionmaking, the perception of and potential for bureaucratic abuse and/or bias may be sufficient to discourage participation. "

This is only true if you assume that the 99% who posts 50% of the content actually know the inner-workings of Wikipedia. I had no idea Wikipedia was structured that way so in making posts on wikipedia I've never felt any form of discouragement as a result of the structure. Further, I think that even if someone is aware that the structure is hierarchical, wouldn't it still make sense to post the information on the website anyway? Worst case scenario, it gets taken down or edited by the "wikipedia elite". But, isnt the possibility that it stays on the site worth putting it on there; I mean, it won't be on the site if you don't put it on there, so you may as well try to get it on there
