Diigo:  Collect and Highlight, Then Remember

Diigo aims to dramatically improve your online productivity.   Building upon the strengths of award-winning Diigo V4, widely regarded as one of the best and most popular social bookmarking, web annotation, collaborative research services,  Diigo V5.0 has added additional data types (screenshots, pictures, notes, etc) and platform support, such as Chrome, Android, iPad, iPhone, etc.  With Version 5.0, Diigo moves one step further towards its vision of providing the best cloud-based  personal information management (PIM) service that enables users to collect, highlight, access and share a variety of information, on a variety of devices.
