The coolcat blog is a great website for teachers to stay current and for librarians to see what new ideas are happening in classrooms. When I search Library2Play I saw the blogs that were made by people regarding the Library2Play site. There were even comments about the different 'things."
I especially like the site http://libraryblogs.suprglu.com/. I find the site easy to use and especially helpful. It seemed to have the most information for what I would be interested in. I would have to say that the site http://www.topix.net/ was the most user friendly. I loved that it recognized my location and suggested sites for me.
I did not find any of the sites 'hard' to use but the site http://technorati.com/ was the most overwhelming. It seemed to have a lot of information and could make you unsure where to even start.
