The immediate benefit from Delicious is the fact that users no longer need to use the browser that's running on their desktop or laptop to keep track of sites. If you're at work but need to bring up a link you found on your home computer the day before, you can find it easily if you thought to save it on Delicious. If you're on the move, whether you're at the library or even on vacation in a different country, an account with Delicious could make it easier and more efficient to recall bookmarks and save them for later use.
But Delicious is more than just a simple place for people to store their favorite Web sites on one account. There's a social, Web 2.0 aspect to Delicious that adds another level of interaction and communication to bookmarking. When you save a bookmark, you have the option of sharing it publicly. For instance, if you find a great article or blog post and save it publicly, anyone else searching Delicious can view the same link. On top of that, if you post a bookmark, other members can add that link to their set of bookmarks, too. Bookmarks that are popular get highlighted, and what naturally happens is that content that's considered to be more interesting or useful to users tends to make it to the top. You can go the opposite way, too. In other words, if you don't want anyone else seeing the sites you bookmark, you can mark them as private. Then, only you will be able to see your bookmarks.
Tags also play a big part in the social-media aspect of Delicious. Aside from helping you remember specific categories with simple, one-word descriptors -- for instance, an article about polar bears could have the tag "wildlife" or simply "bears" -- popular tags create a collective library across the site for people to share similar interests. These tags become their own URLs when you add them, so if you wanted to see everyone's bookmarks on wildlife, you can just visit http://delicious.com/tag/wildlife. You can add as many tags to a bookmark as you want; the only requirement is that the tag has to be one word since the tags will eventually become part of the URL. If you're tagging a subject on something with more than one word, it helps to use abbreviations or dashes, and Delicious provides a list of popular tag names when you're saving or editing bookmarks to make keyword selection a little easier.
