Web 2.0 – What does it really mean?

the video

Web 2.0 is an idea. An idea that stems from the knowledge of what the 'web' is. Web meaning the internet, the world wide web, connecting each person in the world together. 2.0 refers to a new version, which is partially true in this sense. The web has changed since it's creation, and it's now defined by the users rather than ISPs. It's user driven, about sharing everything possible, and learning as much as you can.
