Thing 17

I don't know that I see a practical use of social bookmarking for my classroom.  I think for me personally it is a great place to find sites and reviews of sites that I can then link to on my classroom webpage by subject or topic.  This way I can review the relevance of the website to the topic or class and determine if it is useful for my students.  

It may just be a bit of the control freak that I am (and think most teachers are since we are master and commander of our classrooms), but I want to make sure that if my students are going to a web page for resources, it is worth their time and relevant.
