When I recently stumbled upon Diigo.com I found the perfect solution for bookmarking and annotating web pages instead of saving them as PDFs or wasting paper and ink by printing them. Diigo.com and Delicious.com work similarly whereby you can annotate, tag, and share bookmarks with other members of the site. The site provides a downloadable toolbar for Firefox, Flock and Internet Explorer web browsers for online browsing and interaction. For other browsers, including Safari, it provides a bookmarklet similar to the toolbar but not quite as feature rich.

I want my desktop printer to be nearly as archaic as film-based cameras.

So, what’s new in V4 (click to learn more)?   Building upon the strengths of Diigo V3, version 4 adds significant features, usability and flexibility: New user interface — Users of version 4 enjoy an all-new web interface that reinforces Diigo as a powerful personal and team research tool. The three main areas — My Library, My Network and My Groups — relate to the key value propositions of Diigo: Research, Sharing, and Collaboration.  New display options — compact, standard and power edit — also make the rich feature set more easily accessible.

This is like building a personal wayback machine of important webpages.   Some examples of uses for this new features are:  archiving of online receipts, promotional ads, client media outreach (for marketing and PR) archiving and reporting, and a wide range of time-progressive reporting of online data.

Integration, filters, sort options, greatly improved support for tags, highly focused search results, group snapshots and other refinements make Diigo group work both productive and enjoyable.
