Web 2.0 generally refers to any website where the users can interact, store and add data and communicate with other members. It can be as simple as a blog or as complex as a social networking website. You can add Web 2.0 features to any kind of website, even corporate websites.

There is no definitive list on the features a Web 2.0 site should have, but they may include some or all of the following:

• Visitors can create a user account
• People can add comments to content
• People can rate the content
• People can send messages to one another
• Users get their own profile which other users can view
• Users can 'follow' or 'friend' other people
• Users can add their own content such as text, images, video and audio

Essentially it is any feature that can create a community feel, that members get a sense that by going on the website it is not a passive experience. Another way of defining Web 2.0 is that you are creating a framework around which the members provide the content. If we take a social network site for example, there would be no content if there are no users.

Web 2.0 can also refer to a certain style of design, although this has since evolved and a 'web 2.0 look' can seem a bit dated now as it was popular 2-4 years ago.
