Web bookmarking and research tool Diigo is announcing the launch of Diigo 3.0 today. We initially reviewed Diigo when they launched at DEMO 2007. Diigo is a bookmark tool but what I like about Diigo is their WebSlides feature. It basically makes a live PowerPoint-like annotated presentation using media from across the Web. Back in September I thought the tool was perfect for Web agencies, and I stand by this claim today.
One of the new features of Diigo 3.0 is collaborative research. Team members can bring together links they find across the Web for comments and annotation. There is tagging and sticky notes that the team can participate in to make the presentation stronger.
The other major update is the addition of more social components. If you install the Diigo toolbar, as you browse the Web, you can see what others think of the page including comments, who bookmarked the page and what other similar sites and pages they have bookmarked. It's all about discovery and Diigo has done a great job in this area.
