The whole "Like" idea is potentially superior to link sharing, bookmarking, social bookmarking, polling and other technologies that millions of people use every day. If the concept really takes hold, it could become the primary way for people to share content, links, opinions and much more.

Google +1, Facebook "Like" or some other service we don't know about yet could one day rise to dominate the lucrative new world of social influence.
