Social Bookmarking

 I had no idea this existed until I was reading for my technology class. Social bookmarking is essentially a way to easily share the webpages you bookmark, with select people, automatically! I am going to test out Diigo, which is one that my textbook shared as a free extension. I liked that it allows me to highlight on any webpage and it also allows me to make notes, and organize my bookmarks. 

So far I have been struggling to figure out how to share it with others within the extension. I am wondering if that isn't an option with the free version.
