At first, I was pretty confused as to how to use Diigo. I'm still not aware of its full potential, but I get that you can like blogs and links and read other blogs and links through the tags. I really like the Diigo toolbar though. When I'm browsing the web, if i find an article I like, I can automatically save it to Diigo or highlight parts of it and save that. Also, I can post a 'sticky note' with my thoughts as I'm reading the article, directly on the article page! That's a huge bonus that I'll share with my students!! Also, I like how I can save from one computer and go to the diigo app on my iphone and my articles and photos will be there too. I have more to learn with this app, but I'm really liking it!
