Week 6, Thing 13 Tagging Del.icio.us

I have tried on 2 separate days (July 16 and 18) to get into the Del.icio.us tutorial only to have the computer screen show that the 12 minute presentation is unavailable. Tagging seems to be an "unstructured, free form" association of keywords to find online content. Flickr and Library Thing were pointed out as being 2 forms of tagging. I checked out Del.icio.us URL, saw its social bookmarking listings, and pulled up the Shifted Librarian site showing user descriptions and commonly used tags. I could see personal use for tagging when looking for particular pictures in photo albums by using keyword descriptions to find certain shots.
