Web 2.0 is considered to be the evolution of websites for contributing, sharing and editing information online. Some good examples are wikis such as Wikipedia, video sharing such as YouTube and blogging tools such as Google's free Blogger. Community websites are popular for allowing people to share and disseminate information around a common theme. MySpace and FaceBook are two common community websites.

Some people wonder what Web 3.0 will be like. It is thought this will be some form of the semantic web where all the collective information is organized and accessible at a highly customizable and personal level. Web applications will take on more characteristics of artificial intelligence and can tailor information to users in very specific ways.
