There is no question that Diigo beats all social bookmarking services hands down. What Google is for search engines, Diigo is for social bookmarking. Diigo has got something for everybody, whether you are a casual surfer, a researcher or an enterprise, their services cover just about everything you could ask from a Web2.0 app. Bookmarking, sharing, blogging, knowledge base management, team collaboration or presentation … they have given much more than we could desire from a single app.
