But the feature that catapults Diigo into the stratosphere in my mind is its ability to search annotations. If you do any blogging, I'm sure you know why this is such a helpful tool. Now I can annotate facts and figures on web pages and tag them. In the future, when I desperately need references and links for an article, I have a whole database of searchable stickies and bookmarks. When I return to the web pages I've annotated, there are all my notes and highlights. Also, since all of my Diigo data is out in the cloud, I can access it from any computer.
