What is Web 2.0?

To understand what web 2.0 is, first we should take a look at defining web 1.0. Web 1.0 is a designer and user relationship which has a designer creating a website which displays some kind of information and then the user reading/viewing the information.

Web 2.0 on the other hand has a relationship in which the designer creates a system allowing the users to become designers as well, uploading and changing their own content perpetuating the circle of information exchange. Examples of a web 2.0 website would be blogs, social networking sites (Facebook, Myspace ect.), Wikipedia, eBay or DeviantART , generally these websites would be nothing without a large user base to drive them.


Facebook
facebook is a social networking website designed to allow users to create their own profiles, upload pictures, chat and interact within a global community of people.


Wikipedia

eBay
eBay is an online shopping system that allows users to post items that they wish to sell and then have other users bid to buy for, there is also sometimes a "buy now" option that negates the auction to pay a specific price instead. this website has lead people to be able to start online businesses and allowed pre-existing shops to expand to a larger online community.
