Paul pointed me in the direction of another firefox extension the other evening called Stumble Upon
The concept is very simple.
You choose your areas of interest and can then “stumble” from one site to another using the little button in you firefox toolbar.
As you view sites you can express your approval or disapproval.
It’s a great idea if you like finding new and interesting (and boring) sites randomly.
Stumbling – an alternative way to browse
