I wish I could upvote your indvidual descriptions. > #5: Wiki. More pagerank than God. This one would have got most Karma. Wikipedia is an excellent example of self-generating pagerank. More people link to it because anybody can edit it, hence would be "fair" and "comprehensive". And just because a particular Wiki article gets popular, it starts getting more attention (by experts) and hence becomes fair, comprehensive and detailed. The cycle repeats.
