DIIGO: At first I wasn't sure this was going to be cool, but then I changed my mind. Diigo is a way to do research online and create a virtual "web report" of content and links which you can use later to collect information and/or share with others. Imagine doing research on a topic like "HTML programming" and bookmarking each page of relevant information with highlighted portions that you can evaluate later. If you can imagine it, then Diigo is where you sould spend some time. I dig it, you might too.
