I have always liked the approach of updating certain content on-the-fly in a web page without the need of reloading the entire content. This approach has been around for years and has fairly recently been nicknamed AJAX(Asynchronous JavaScript and XML).

For those who involved in web development will be very interesting to know that AJAX became so easy to use that even person without developer experience could use it quite easily. 

Try this ajax class that only requires insertion of it's link in head section and some VERY simple modification of regular links.
