Social Bookmarking Post - Week 4

I had heard about del.icio.us but had always wondered "what's the big deal"? Why are folks excited? Actually getting in there and working with it, I can see the allure. Right now I think it will be used, at least by librarian, or maybe at least by experienced librarians as a convenient place to keep and organize bookmarks. Many of us are used to a more controlled indexing structure and the advantages that provides. But as time progresses, we'll probably loosen up and take advantage of the "social" end more.
