Diigo is a social annotation and networking service. It is combining social bookmarking, clippings, in situ annotation, tagging, full-text search, easy sharing and interactions, Diigo offers a powerful personal tool and a rich social platform for knowledge users, and in the process, turns the entire web into a writable, participatory and interactive media. I just registered Diigo, I have time to know more features. It is free but need invitation for register.
