First, the option to look up people in different ways such as their real name, user name or how they tagged something allows for better networking. I also am very impressed with the idea of lists. Although, I am still trying to figure out how to implement them, I am excited that this would be a great tool for the classroom use for research and or sharing. In addition, I have just spent hours trying to figure out the snapshot feature. I think I will break down and watch a tutorial. However, I truly like to try to figure things out on my own. It seems to me I am just hitting the surface of Diigo. Delicious does not seem to have as many bells and whistles.
I have always liked Social Bookmarking. I wish we could get more teachers to network and therefore share tags. If you had a set of tags that were standard, you could easily create websites that coincided with curriculum, standards and which time of year they were for. Social Bookmarking is a great way to collaborate and find some great treasures.
