Here is a screencast by Jon Udell on del.icio.us. I've been hearing about del.icio.us a lot in various blogs. I did not know how it would work for me, and I did not have the time to play with the service. But after watching the screen cast I got a nice overview of the wonderful world of social bookmarking, and well, I've registered with del.icio.us. Watch the screencast, and decide if its a service you could benefit from. I've actually been looking for this kind of a service for a while now, I just did not know that del.icio.us is the answer.
