If you were to see my new office, other than the walls, you would see that it is largely bare since all I have is on the cloud. Part of the reason is because I use Diigo to save and categorize all of my sites which you can see here. What I really like is that you can see what I have saved and then see others that have saved similar sites. But you can also lock down a link so no one else can see it so you can save your passwords or save clues as I do.
The video above first gives an overview of what you can use Diigo for and then at 4:43 it begins to show you how to save sites and put them in categories.
