Diigo, a Reno, Nevada based startup I previously covered when it launched Web Slides, just launched version 3.0 which offers an integration of a number of social bookmarking and research services that create a powerful set of community tools.
What is new with Diigo v3? The Diigo v3 launch includes a completely new user interface and code base, hundreds of new features and most notably a tightly integrated social networking with knowledge-sharing. This improvement puts Diigo in direct competition with delicious and other web 2.0 social bookmarking products.
Check out this quick demo video about Diigo v3 and find out just what it can do. Please note though, this video surprisingly showcased a screen-shot of TechCrunch and not SOMEWHAT FRANK - there must be some sort of mix up. :) Nonetheless, Diigo v3 is pretty impressive. I like the way that Diigo enables users to create lists of bookmarks that can then be viewed a number of different ways (list views, web slide view, etc). I also like its bookmarking toolset as it offers a number of innovative ways to capture and annotate content.
