the aggregators lead you to articles or sites that you want to save and remember. And for that, I have another favorite tool: Diigo. While it would be easy to describe Diigo as a social bookmarking service, that would make it sound too much like Del.icio.us or Furl or Reddit (all of which I’ve tried and tired of at various times). It’s really more of a research tool with social, collaborative features. Most importantly, Diigo (which is operated through a toolbar that works in the Firefox, Internet Explorer and Flock browsers) allows you to bookmark pages on a list that’s saved forever online and accessible from anywhere. No more messing around with your Web browser’s built-in bookmarks, which won’t be available to you if you happen to log into the web from a different computer. Just as fun, Diigo makes it easy to highlight passages within a Web page—so you can return later and see what it was that caught your attention—and even attach floating “sticky notes.”

You can also attach tags to your bookmarks to make them easier to find later on, and you can click on individual tags to see what other Diigo users are bookmarking publicly under those tags. (As a journalist, I’m secretive enough about what I’m researching online that I tend to keep my Diigo bookmarks private.) In late March, Diigo rolled out Version 3 of its system, which includes enhanced “social browsing” features such as the ability to see how other people have annotated a given Web page, follow what your friends are bookmarking, or subscribe to other users’ bookmarks based on tags.
