The role of web 2.0 technology

The term web 2.0 is used to distinguish today's internet from the way it used to be. First generation (web 1.0) websites were created and edited by technically skilled people and made large amounts of information available for the general public.
While large amounts of information are certainly still available, a key characteristic of web 2.0 technology is that non-technical people can quickly and easily create and share online information. Web 2.0 led to the development of social networking sites such as YouTube, Facebook and Twitter.

But it's not likely to end there, web 3.0 technologies are on the way. Web 3.0 has been described as "giving the internet itself a brain".
