Thing #15 - Tagging

Del.icio.us is an interesting site. I've never really played around there much before, nor have I 'tagged' much on the internet. I can see how this would be good for research. Not only can you comment back and forth with people on a topic, but you can see what others post in relation to the subject. I saw many sites having to do with the current state in Egypt and how they shut off the internet.
