It is easy to think of Web 2.0 as a single technology and it is often used as a marketing tool to add a little oomph to a new development but it would be more appropriate to describe Web 2.0 as a collection of technologies (and ideas) that cover diverse areas from Interoperability, Accessibility to Usability and Design:

• Interoperability
  Between applications or data, between presentation and data layers or between users of information
• Accessibility
  Information that is easy to access and deal with
• Usability
  Information that is useful, convenient and capable of being used (and re-used)

Some people believe O’Reilly and MediaLive came up with the term “Web 2.0” whilst others do not (“O’Reilly & MediaLive Didn’t Coin the Term – Web 2.0”) and if you read Wiki it will tell you that Web 2.0 means different things to different people, but I believe that the general consensus it that Web 2.0 is about people and putting people in the information driving seat.
