Web 2.0 refers to webpages where the user can edit the content. This differs to the original static websites that simply displayed information. On the web today users are able to post comments, add reviews, photos and video.
Examples of websites that use web 2.0
Amazon - product reviews
You Tube - User created videos, then other users comment and rate
Social networking sites - Facebook etc
Google Docs - Applications via the web, sharing files, access from any computer
Wikipedia - Anyone can edit articles
Advantages
There are many advantages of web 2.0 over static webpages. User reviews mean that potential buyers can see what others thought before buying. You tube provides a place for people to show their work to an audience, that was previously only available to film studios, as well as allowing family and friends to view home videos. Social networking sites allow people to keep in touch. Google Docs means that people can easily collaborate on work, as well as providing a free version of basic software packages. Wikipedia allows a variety of experts to share their knowledge on topics to create a comprehensive information bank.
