Chris has been teaching for over 20 years and is currently the ICT Integration Specialist at Presbyterian Ladies College in Sydney, Australia.

Using simple examples from a number of tag-driven websites, this presentation looks at how tagging and the subsequent creation of folksonomies are changing the way we think about information. Starting with obvious tagging systems used on sites like Flickr and Delicious, it examines how tagging enables information to be classified, sorted and managed in ways that make it more accessible, easier to manage and more self-aware. It also explores how tags can be aggregated across large collections of information to provide a snapshot into the overall zeitgeist of collective thinking.
