Web 2.0
Web 2.0 has various definitions depending on who you speak to, where you research and when the definition was given. Of the definitions I've encounted the one I am most comfortable with is this: Web 1.0 was largely 'read only' content, Web 2.0 is more interactive and therefore 'read and write' where the user is involved in creating or 'adding value' to the web application. Earlier definitions included things like 'the name of a series of conferences in 2004' where the web, after the dotcom bust was starting to make a resurgence in the business community and sparking a renaissance in the web development sector.
Examples of Web 2.0 would be things like Facebook, Myspace, Wikipedia, Twitter and Ebay
Interactive Design:
Interactive design can also be seen in a number of ways. It is at the same time a discipline of 'defining the behaviour of products and systems that a user can interact with', and more simply, it is essentially 'story-creating and telling' where the user has input.
Some good web design examples include:
Information/Instructional Design:
A simple definition of Information design is transforming, organising and presenting data in a way that gives it meaning and creates knowledge, rather than a huge load of disorganised facts and uninspiring rhetoric.
Examples of information design include:
The Vietnam War Memorial in Washingtom DC
Street Directories
