So how is it used?

Most websites use it to validate information used on forms before sending it to server side programs

Examples are online banking, shopping and webbased email. To make sure you havent done anything silly

As i have no knowledge (yet) of server side programs and this goes also beyond the scope of the talk

I will just concentrate on effects used to modify the HTML document

I use it to create dynamic content to brighten up the webpage. As Oregano (1 and 2) only supports the lowest DOM levels its rather limited but effects can still be achieved with a little imagination
