Building on the Wisdom of the Crowds Greg Linden quotes Chris Anderson: "Amazon and Google ... have built their brands on the power of their filters ... Google's search algorithms [and] Amazon's recommendations ... are nothing more than the wisdom of the crowds, the statistically measured opinions of millions of ... people. That's why we trust them." Greg adds: "Systems like Amazon's recommendations and Google's PageRank implicitly share the wisdom of the crowds. Collaborative filtering-based systems like Amazon's recommendations use algorithms to find people with similar interests and share their wisdom. Google's PageRank algorithm mines the link graph -- links people made between web pages -- to surface authoritative and useful sources of information...Implicit systems like Amazon's and Google's surface the wisdom of the crowds anonymously, quietly, and with no effort from users."
