    10. 10. Social bookmarking There are a number of sites for this. By far the most popular is http://del.icio.us Rather than bookmarking sites locally allows you to have access to your bookmarks from wherever you are. This is a small example of the “ web as desktop ” philosophy.
    11. 11. Delicious demonstration http:// del.icio.us
