What is web2.0?

Web 2.0 refers to a perceived second generation of web development and design, that facilitates communication, secure information sharing, interoperability, and collaboration on the World Wide Web. Web 2.0 concepts have led to the development and evolution of web-based communities, hosted services, and applications; such as social-networking sites, video-sharing sites, wikis, blogs, and folksonomies. - Wikipedia, 20 April 2009


Web 2.0 defining characteristics• the Web as a platform, web services which use the browser, easy to use

• User generated content the driving force

• Easy to create, distribute and share content, often collaboratively via RSS

• Folksonomic content classification using TAGS

• The "Network Effect" - services improve the more people who join - e.g. del.icio.us, flickr, Facebook

• Social Networking

• Makes it easy to find other users with similar interests and form online communities – Social Software

• Mobile a driving force

RSS – The distributed model• RSS is the connecting fabric of web2.0 services,

providing the conduit for information flows between distributed networks.

• Means to subscribe, syndicate and remix (mashups)

• All about the connected information flows between decentralised nodes, characterised by a willingness to share, mix and feed.

Tagging• Tagging is a method of categorisation whereby

key words are assigned to web based resources by users

• Each user "tags" the resources arbitrarily according to their own personal preferences.

• tags are shared (rss) & grouped to form knowledge sharing networks
