Difference Between Delicious and Diigo

As a bookmarking site, Delicious is great for its simplicity - I find it to be incredibly easy to use and I use it ALL the time! Diigo has many more complex, yet wonderfully valuable tools that I will easily be able to use in order to not only share the websites I've found with students and colleagues (and anyone else who is interested) but also to highlight and make notes on important ideas for my own future writing and researching! As I have become overwhelmed by the amount of information that is out there, I truly appreciate a place such as Diigo to be able to organize, manage and manipulate all of that information I find rather than having it just be "something I once read that was interesting." It takes on another life by being able to digest it time and again and share it with others. Additionally, Delicious is actually just what I've been looking for, as I have been coyping and pasting websites into Microsoft Word and saving it on my USB key so that I could always bring those website with me to other computers I'd be working on. While I felt creative at the time, to figure out how to organize myself a bit, it now seems so incredibly archaic!
