Rated 5 out of 5 stars
Recently released Version 3.0 may be the most intuitive tagging, saving, snipping, notetaking and commenting web app ever. This version should probably be 4.0, because it improved that much over 2.0 version. The toolbar comes with a sidebar option that is a true complement, not a redundant vertical version of the toolbar. The entire interface (toolbar, sidebar, dropdowns, context menus, etc.) including the newly redesigned website, reflects a thoughtful understanding of user interaction with web content. The website addes a truly collaborative/group thinking type dimension to content tagging and searching that I have not used much yet, but appears equally well designed. Kudos to the Diigo team!This review is for a previous version of the add-on (0.5.2007021000).
