In the words of Tim O'Reilly, coiner of the very term, Web 2.0 is a where a network is the platform. It's where users add value, and the goal is to create databases which only get better with an ever increasing number of users.
In other words, Web 2.0 is where users gain control of the interface.
Web 2.0 allows users the freedom of talking to each other, instead of just being talked at.
No longer do users passively sit back and simply absorb information, they now explore, contribute and communicate with others.

Some great examples
- Myspace
- Wikipedia
- Google Earth
Facebook:
Facebook is a communication platform that allows users to search for friends and family with Facebook profiles, and communicate in ways similar and dissimilar to real life.
Messages and comments can be left, photos can be posted in albums, and a myriad of applications can be added to personalise and enhance interactions between users. Not only can users give virtual gifts, flowers, and try to measure their IQ against their friends', they can also engage in virtual motorbike and car races for points, nominate friends for novelty superlatives, and send each other movie clips and dedicate songs - and so much more.
Google Earth:
Google Earth enables users to view any part of the earth and zoom in, find points of interest, and other details specific to the local landscape. As an additional bonus, if viewing the Eiffel Tower from above isn't enough, users are able to click on the camera icons and view images others have posted from different distances and perspectives! Almost as good as being there - and possibly with a greater overall visual experience than an individual could have of the icon in the flesh.
