PageRank has a limitation though. Wikipedia & Digg have the same limitation. They are easily lead astray by mass misconception.

If it’s deliberate you may call it a GoogleBomb, or psyops, but often it is not. The writings of convincing but wrong thought-leaders can spread further and faster in this modern era. On balance I believe we are much better off, but I am still sometimes concerned about how quickly harmful memes can spread, particularly among those who seem to have no natural defense.
