That's the number of web sites I have bookmarked on my work computer. I learned this after setting up my Delicious account and importing my bookmarks. Upon visiting a new web site I do tend to bookmark it if I find it interesting or useful so that I don't have to try to remember it, and I knew I had a lot of sites bookmarked, but wouldn't have guessed more than a hundred. This makes me wonder how many of these sites I actually use or have even visited lately. Some, of course, I do visit often. DLTK is a site I often go to for craft ideas and coloring sheets. There are several sites I go to for fingerplays, Jean Warren's Preschool Express being one of them. Other sites, such as the local schools or Mapquest, I use from time to time and are worth saving. Then there are some that I have to wonder why I saved them to begin with but won't delete them for fear that I'll want to find them some day.
I haven't yet taken the time to explore much of Delicious but certainly I see the advantage of having bookmarked sites not just on one computer. I have a somewhat different list on my home computer than I have at work and there are times when I would like to find something that I have on the other computer. Several years ago my home computer crashed and I lost all my bookmarks. I could easily see recommending this service to patrons for saving their own list of bookmarks. But in making use of Delicious to provide a list of bookmarks for our patrons I have to wonder how this differs from simply having a list of links on our web site.
