An interesting development is that Facebook is becoming a platform.
Facebook started as a social network, however now it is being integrated into websites all over the world.
Now facebook is becoming more “search” than “social”. This means that when you want to buy a DVD, you now see your friends purchase history and recommendations on 3rd party sites and make your “search” decision, socially.
This is what I see when I visit http://www.yelp.com
What is the application of this? Think.
