Learning about the social part of WorldCat was indeed interesting. Using this feature of WorldCat allows more social interactions and makes the catalog feel more personal especially with the ability to add the WorldCat search widget to your blog or facebook.
Creating lists is a lot of fun I made one about gnomes. After making one list I went ahead and made a couple more. Having the lists be search able is also a great feature because you can see what is out there or add your own information. Watching lists is helpful so you can keep track of changes and get new information.
This aspect of WorldCat could be very useful to libraries and library patrons. The best feature for librarians and library patrons is the ability to make lists. I know these lists were helpful to me and would likely be helpful to library patrons or librarians who are searching for materials. Searching through lists may show someone a starting point to what they are researching or may even lead them to a new idea. Another use for libraries would be using lists to show patrons the wide variety of resources available on a variety of themes or topics.
Overall trying out the social aspect of WorldCat was informative, educational and even a little fun. This thing could indeed be very useful in any library setting.
