Web 2.0 is a catchword for the new internet paradigm that is just starting to shaping the way you work and interact with information on the web.

Today's entry will explain the various different examples that Web 2.0 has to offer. As mentioned Web 2.0 is the product of the open source which offers practical accessibility to a product's source (goods and knowledge). It allows new information and business opportunities to further develop information, provided before. Web 2.0 allows data to act as its own entity, which can be changed, altered or remixed by anyone for any specific purpose.

Web 2.0 is built on technologies like Ajax, a web development technology that is based on JavaScript and XML; which is used for creating interactive web applications or rich internet applications. This technology enables a user’s pages to function more like a desktop-based application, as you can retrieve server data asynchronously within the background without interfering with the display and behaviour of the existing page. Dion Hinchcliffe who studied various online products and services in the development stage, particularly mostly on Web 2.0 wrote:

"As important though, is the tangible value which the Web 2.0 provides today:

- Leveraging The Long Tail. Amazon and eBay used this idea to build companies worth billions and billions. This is how. Web 2.0 provides both the audience and the services.

- Small Pieces, Loosely Joined. Monolithism is dead, we can't build big stuff like that any more. It's not agile nor can what you build be aggregated, deliver sustained value, or even survive for long.

- Self-Service and Participation. Fostering this lets you capture new value in your Web 2.0 apps 24 hours a day. Examples: Tagging, ranking, trackbacks, reputations.

- Radical Decentralization. Single sources of function are single sources of failure and are unacceptable now. And they don't scale to either deliver or capture significant value.

- Emergent Behavior. Your Web 2.0 functionality can be reused, remixed, aggregated, and syndicated and the resulting value reintegrated back into your application."

RSS is also another cool technology that Web 2.0 endeavours. As you all know RSS allows user’s to receive automatic updates when a site changes or updates information; provided if you have subscribed to the site's RSS feed.

Other examples of technology that Web 2.0 strive on are:

• blogging: allows people to create personal online blogs (eg. http://blogger.com)
• tagging: a feature which helps organise and find URLs (eg. http://del.icio.us, http://flickr.com)
• social bookmarking: enables you to create a media monitoring tool, for your organization's internal. (eg. http://bloglines.com)
• Wikis: Wikepedia- largest free built encyclopaedia that allows anyone to update on it (eg. http://wikepedia.com)

Below are just a few Web 2.0 logos that are defined by internet users.
