Diigo is an online bookmarking tool with a twist. Sometimes, merely saving a bunch of tagged Web sites to a list of favorites is not enough. Ever wanted to highlight one cool corner of a Web page? Do you wish you could scribble on various Web sites to collect recipes, plan a vacation, or write a big research paper, then share your notes? Diigo can help you do that.

Diigo's plain text interface is as simple as that of Del.icio.us, yet with additional functionality. For instance, Diigo lets you select a bunch of bookmarks at once and change their settings; Del.icio.us does not.

Diigo looks as basic as Del.icio.us, but ease-of-use tweaks make a big difference in convenience. For instance, you can select all items on the page and change their settings at once, which Del.icio.us doesn't allow. Advanced search features look within the text of a page, as well as at tags, titles, and your annotations

Diigo, which has a cameo in the Wesch film (nominated for best supporting web ap), offers itself in its latest beta incarnation as a site for sharing annotations in the form of sticky tabs. Thus, the web becomes notable. I have already begun to use this site in my classes for commenting on blogs my students write. But why not use this tool, in the spirit of Writer Response Technologies, in the spirit of Flickr fiction and Tag Cloud Art, as a tool for creating fiction. Because Diigo offers the social annotation of sites, there is the possibility of creating narratives, parasitic though they may be, upon the websites of others.Following the genre of annotation fiction, discussed at length below, why not turn the web into a means of characterization, to turn web reading practices themselves into ways of examining the ergodic, interiority of our characters, or to stitch together tales of paranoia in the way that various ARGS have. If we use the tool in this manner, the Web will be, as author Roberto Leni has put it, our palette.

I’ve been using Diigo and its less sophisticated cousin, del.icio.us,

Shortly afterward, I discovered Diigo. Not as many people use Diigo, but for those of you who blog or prefer prefer to read page annotations from other viewers it is an improvement over del.icio.us — plus it will import and update your del.icio.us bookmarks even if you use Diigo almost exclusively. For personal surfing and blogging purposes, Diigo is the best choice

Diigo’s group feature gives researchers an awesome platform for managing research sources and collaborating with others. Basically a Diigo group allows multiple users to share links related to the group’s topic and offers a forum for conversation. That in itself is a fabulous research tool, but that just touches on the capabilities of a Diigo group.

Diigo is by far the most fully featured social bookmarking site in this list, and offers several unique capabilities. The most notable feature is that users can highlight text right on the page, as well as make annotations via a “sticky note” for later viewing.There are also other very useful features. I particularly liked the sophisticated and advanced search option for doing a keyword search of one’s own or public bookmarks. On that page you can limit a search by a phrase, and restrict a search to a URL, title, comments or highlights. You can even search “on” specific users as wellNote that when you place a “sticky note” to comment on a page for your later viewing, that note is viewable by anyone else in the Diigo community that views that page too! .There are some other interesting and unique features on Diigo. For instance, when highlighting a word on any page with Diigo’s bookmarking tool, a drop down menu automatically appears that allows users to search for that highlighted word on various search engines, social bookmarking sites; blogs, on the active site and more. I also had much more control in formatting when saving a page; and had an option to forward the page to another person as well.What about the all important group feature? Well, Diigo rounds out its offerings very nicely by just this month launching its “Groups” function. That feature looks to be a clear and elegant way to allow anyone to set up a private environment for sharing your bookmarks. Ultimately, if you combine the Web annotation capabilities with the ability to share in groups, Diigo has created a very enterprise friendly social bookmarking service. And, according to a spokesperson at the firm, this Groups function is “just the first of many more advanced group collaboration functions that we will be introducing in several phases” So we look forward to staying tuned!My Grades:Group Function Capability: AResearch Value: A-Design/Interface/Ease of Use: A-Fully Featured: A-(only missing “related users” and “larger topics”)
