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.
