I think everyone would agree that Diigo is great for research, social bookmarking and networking. This week I have found another great use for Diigo. I have started having students bookmark their Prezi Presentations in their class research groups, thereby bringing it all together in one place. This allows members of the group to view each other's work and better yet, allows me to open each presentation up directly from Diigo, as each group gets up to present, without the hassle of logging in and out of different accounts. It also gives me a one stop method for assessing their work without having to deal with emailed links.
The more I use Diigo the more I love it!
Now if I could only find enough time to dig through the other Diigo groups I belong to.
