web 2.0

Web 2.0 is the term used to describe the new usage of the internet as opposed to web 1.0. As technology has changed, so has social usuage and rapid, rapid expansion has led to a whole new way we use the internet. Web 2.0 is typically more user-interactive, due to people having much more powerful and usable PCs. Videos, social networking, interactive java/flash games and apps, and online games such as MMORPGs (e.g world of warcraft, Counterstrike and Second Life).
The definition, according to According to Tim O'Reilly: (wikipedia.org) is

"Web 2.0 is the business revolution in the computer industry caused by the move to the Internet as platform, and an attempt to understand the rules for success on that new platform."

Interactivity has become a much bigger part of the way we use the internet; we now comment on youtube vidoes and chatting to people on formus about pretty much anything without a second thought.

A problem with this rapid expansion is that there is no limit to the things we can do within reason and this could lead to adverse consequences as people with 'contreversial' ideas can now freely distribute theie thoughts to the world i.e a much larger proportion of people from an almost annonymous position.

As computers get ever powerful and capable, i think we may at some stage enter a new era of internet usage: web 3.0 (or 2.1 whatever) and this may hold other potentially useful or advese consequences for the world.
