What are WIKI'"s, Blog's, Micro Blog's and RSS

Wiki: A web-based mechanism to store information, it can be edited by many different users (sometimes using an authorisation system). The best example is http://www.wikipedia.org/
Blog: A web-based mechanism to allow an open discussion on a topic. http://www.farq.co.nz/ (for a laugh!) Alternatively, you could try a more traditional blog site e.g. http://transportblog.co.nz/
Micro blogging: Similar to a Blog, except the comments are usually smallier in size. An example would be http://twitter.com/
RSS: “Real Simple Syndication”. It is a format used to disseminate information in a standard way. It is based on XML. Most news websites have RSS feeds available, e.g. http://snowreports.co.nz/syndication/xml/allfields_brief.cfm
