What Is Web 2.0?

Web 2.0 is what the Internet has evolved to. In this day and age the Internet focuses on interactivity. The ability for users to collaborate and interact with each other has become one of the main purposes for accessing the Internet. Web 2.0 is made up of technologies that enable such interaction between users on the Internet. Examples of these technologies include blogging, social networking, Wikipedia, and podcasting. No longer is the Internet used for reading static information; it is now used to share music, videos, and interact in new and evolving ways.

To put simply...

Web 2.0 - it's how we roll.
