Twitter is one of the popular online media. It is a bit like Facebook but there are also some quite important differences.

Where Facebook and MySpace very much rely in communication interaction, Twitter is all about brief updates, the so called tweets.

Exactly because of this Twitter is very useful if you need to communicate in fairly brief messages to a lot of people – or if you feel the need to lead a very public online life.

Keynote speakers on Twitter typically look into these topics as well as, perhaps, the role of Twitter in modern media society, within political debate, in relation to children and teenagers, art and culture, etc.
