Web 2.0  - Digg 

URL:  http://www.digg.com/

This Web 2.0 is really new to me.  I am amazed and feel as though I am in a maze.  Up to this point I have been a curious bystander.

THEREFORE, Digg seemed a bit overwhelming, but I am slowly getting used to it.  This site is divide into broad topic areas.  However, the most 'popular' topics rise to the front page.   In trying to decide how to use this for my classes (economics and math), I tend to think it is going to be useful for critical thinking exercises.  Those will probably be easier to develop for my economics classes by allowing them to be involved with various points of views.
