Web 2.0

I read about what Web 2.0 is yesterday night.  A short definition of the concept of Web 2.0 is that is web based technologies that have allowed for there to be a more cyclical relationship between users of information and creators.  The lines of communication are less top down, flexible and diverse with Web 2.0.  In Web 1.0 most of the content of information was produced by institutions for users to read.  With Web 2.0 your looking at more information coming directly from users and technologies being constantly adapted to users and producers needs.
