Thing 11: Tagging and Del.icio.us:

It looks like tagging will be a lot easier and more flexible than keeping information in folders and will be great for organizing and finding personal imformation. It's also possible to view bookmarks added by similar-minded users that may be of interest to you. Use of Del.icio.us is free and most likely one of the most popular to use. Social networking at its best!

At first, I was hesitant about everyone being able to view anything posted but then read that a user can mark specific bookmarks as private collections. I enjoyed looking over the list of the most popular tags.
