Diigo Exposed

Diigo is an interesting tool that I have begun to use this week.  The layout seems very similar to that of Facebook however it seems to be an internal intranet for the few subscribed to the group.  I liked Diigo though as it seemed a little more intriguing in a small online group setting as opposed to Facebook.  I was able to respond to a classmate's post and check out a helpful website she suggested.  I did feel safer communicating on Diigo rather than Facebook as you have to enter a password, several times to navigate the page.
