del.icio.us is quite simply a treasure. Here's how it works: you sign up for a del.icio.us ID, and then, whenever you come across a site you like, you add it to your del.icio.us bookmarks, which then are shared with the del.icio.us community. Sounds simple, and it is - the del.icio.us community at large has shared literally hundreds of thousands of previously undiscovered Web links; and these numbers just keep on going up.
One of the best ways to discover new sites with del.icio.us is the del.icio.us Randomizer button. It's an easy install onto your browser toolbar and once you install it, you'll find yourself compulsively clicking it to find the next cool site..and the next...and the next.
