Diigo Adds More Research and Collaboration Features

Diigo_logoWhen Mike reviewed social bookmarking, research and collaboration service Diigo last year, he liked its simplicity, its connections with other services, and its wealth of features. Since then, the social bookmarking field has continued to mature; witness the recent purchase of Friendfeed by Facebook, and the numerous ways that bookmarks can be shared on social networks. Even MySpace is getting into the act by syncing posts with Twitter!

The latest version of Diigo has just gone live, and from what I can tell, it’s growing beyond social bookmarking and going for the “kitchen-sink” approach: Add as many features as possible, so that no matter what a user wants, it’ll be there. Among the list of new features are a few that caught my eye:

  • Similar to Iterasi, users can now archive web pages from a particular point in time — even ones that are dynamically generated or password-protected. Multiple versions of the same page can be saved, either as HTML or images. Toolbars to control this function are available for Firefox and Internet Explorer.
  • There are now several options for commenting on web pages — highlighting in multiple colors, and different sizes of sticky notes, all of which can be private or shared.
  • diigo-share-sendLinks to the archived and annotated web pages can be shared via email, Twitter or Facebook, and recipients don’t need any special software to see your comments.
  • Groups can be set up to comment, tag and collaborate on projects.

The site is still in beta, but its redesigned interface is intuitive. Searching and tagging have also been improved, and an iPhone (s aapl) app is on the way. The site is free and advertising-supported; educational accounts are available.

Oh, and by the way, Diigo is one of the few sites I’ve seen that offers an explanation of its name:

Diigo is pronounced as “Dee’go.” The name “Diigo” is an abbreviation for “Digest of Internet Information, Groups and Other stuff.”

If Diigo’s impressive feature list hasn’t convinced you to try it, I’m sure that will!
