 With diigo, you can do most of what you can  with del.icio.us in terms of   saving  links with various tags, connecting to other users who have saved the    same post or used the same tag, and tracking  either users or specific tags (or   specific  tags of specific users) via RSS. Even more, however, is that like Furl,    diigo captures a copy of the page, so if it  disappears from the Web at some   point,  you can access it in your archive. 

 

 But what’s really different is the diigo  allows you to highlight certain   sections  of any Web page you’re on, and also gives you the ability to attach    sticky notes to the site. Those highlights and  notes are then visible should you   visit  that page again. But even better, if you have a diigo account and I have    “forwarded” the page to you, you can see them  add your own when you visit the   site as  well. Think digital feedback on student work. 

But del.icio.us is far more than just sharing bookmarks.  It’s a growing  library of web-based resources that are loosely (but effectively) organized  around tags that are applied by those who contribute.  ..And here is one of  the qualities that I would lump with Web 2.0 applications — that they invite,  rely on, and respect the cooperation and contributions of the community.   Not only are social bookmarking systems like libraries in how they are  collected, but also in that I can check out, so to speak, web resources based on  topic/tag and even based on the contributor, and I can train those web links to  appear automatically in my own web sites and online handouts.  This is new,  this ability to organize dynamic documents that reshape themselves based on the  contributions of others

Some of you might have noticed services like Furl,  Flickr and Del.icio.us  using user-defined labels or tags to organize and share information.... Is there  a name for this kind of informal social classification?".

Folksonomy is the result of personal free tagging of information and objects  (anything with a URL) for one's own retrieval. The tagging is done in a social  environment (usually shared and open to others). Folksonomy is created from the  act of tagging by the person consuming the information.

 

The value in this external tagging is derived from people using their own  vocabulary and adding explicit meaning, which may come from inferred  understanding of the information/object. People are not so much categorizing, as  providing a means to connect items (placing hooks) to provide their meaning in  their own understanding.
