What is Web 2.0?
'Web 2.0' (pronounced "web two-point-oh") is the (slightly annoying) name given to the the recent development of interactive websites that are quite different to the old, static websites.
Many websites on the Web today allow users to:
- share information (e.g. notes and photos on Facebook)
- interact (add comments, chat, etc.)
- collaborate on content (e.g. creating pages on Wikipedia)
- create their own content (e.g. videos on YouTube)
Blogs and Blogging
Blogs can be personal (someone writing about their own life, or their personal views), based on an interest (e.g. football), or some businesses also use blogs to write about new products, etc.
Many blogs have systems that allow readers to leave comments and begin discussions connected with the blog posts.
Some blogs are very popular and have hundreds of thousands of readers, but many are only read by a tiny number of readers (probably just the writer's family and friends!)
Wikis often automatically create automatic links between pages. E.g. if a wiki page exists called 'Camels' and you write the word 'camel', the word will become a link to the Camel page. This feature means that wikis are very useful for creating sites containing lots of connected information.
Wikis are used for websites such as:
Media Uploading Sites
All media upload sites have rules about the type of media that you can upload - you have to either own the copyright to the image / music / video yourself, or have permission from the copyright owner.
Connected users can then share information / pictures / files with each other, send messages, chat, etc.
