Web 2.0: Examples

Below are some of the most prominent examples of Web 2.0:

Del.icio.us – An online bookmarking tool, which works similar to the favourites tab in an internet browser, but allows you to access your bookmarked sites from any computer that is connected to the web. It also allows you to tag your bookmarks and works as a tag based search engine to find pages bookmarked under the same (or similar) tag by other users.

Technorati - A collaborative search site for blogs, which utilises the Web 2.0 principles of collaborative tagging linking and social categorisation to filter blogs.

Digg – A collaborative popularity site for technology news, which displays the most popular articles on the home page. Registered users can view articles and decide whether the “digg” (like) an article or not. They can also submit articles, allowing others to “digg” it.

Flickr – A collaborative photo sharing site, which can be used for personal online storage and sharing with specific users, or for public photo sharing. Photos can also be tagged and many users creating RSS feeds to their photos.

YouTube – A video sharing site, where users can upload videos, view other videos, post comments and even create their own user channel, which can be subscribed to through an RSS feed.

Wikipedia – An online encyclopaedia where the users create the content themselves and then collaboratively edit it in order to create a large collaborative knowledge database.
