Something you should try out. It is a web site that collects the favorites or bookmarks of registered users. Very handy if you use more than one computer. Per bookmark, you enter one or more tags that correspond with that web site. With these tags, links are then made between other users’ tags, which lets you browse through different categories. All favorites and tags are public, so you can see the entire favorites collection of each user, allowing you to discover very useful and original sites.
Registration is free.
Using the Flock browser, the del.icio.us service integrates perfectly with your Internet experience. Just tag the site you are currently on, and Flock automatically connects to your del.icio.us account and enters the favorite and it’s tags for you.
I also use a plugin to accomplish the same in Firefox. It can be found here.
