I've been using the social bookmarking site delicious for about a month now. And I'm loving it! It is a really easy way to create and access bookmarks across different computers or even between the Windows or Mac platforms. The ability to add tags, or keywords, to a bookmark is just brilliant. Tagging is one of the main premises on Web 2.0 sites. There are other features that are worthwhile in creating a free delicious account. I found this great video tutorial to explain the concept of social bookmarking.
