Web 2.0 - it's all about the conversation! (Leaver, 2010).
Web 2.0 saw the transition from personal web sites to blogging / interactive social networking applications. The main difference was the ability to author or create a web presence without the need for technical skills, opening the web up as a more interactive user driven experience.
The driver for web 2.0 was the separation of data content from the formatting aspects of the web site. This was facilitated through RSS - Really Simple Syndication - which enable users to pull the content data from a site and subscribe or integrate that data into their own presentation format.
The publication tools which are synonymous with web 2.0 made the web available for everyone to generate and share knowledge, to join in the conversation so to speak and interact with each other, much more in line with Tim Burners-Lee's vision.
In particular, wikis provide a way for people to jointly collaborate and share knowledge , the most famous of which is wikipedia. Wikipedia in itself is a community collaboration of ideas that anyone can update or edit with the positives being the sharing of previously inaccessible information and links through to associated knowledge, much like what was envisioned by Vannevar Bush way back in 1945. The most obvious negative associated with this type of sharing is the validity of the information, however the interactivity aspect of the web2.0 means that the currency and accuracy of the information being share is constantly and frequently being reviewed.
In the next topic, we will delve further into the world of blogging!
