Everyone knows that a bookmark is a handy way to remember a favorite web page so you don't have to waste time searching for it again in the vastness of cyberspace.
Social bookmarking takes this concept to the next level, enabling Internet users to share their bookmarks with each other in a collaborative fashion. Most often this involves social bookmarking websites where users can create accounts and add their favorite bookmarks, along with keyword tags that help to organize the data and make it easy for others to search.

In a social bookmarking system, users save links to web pages that they want to remember and/or share. These bookmarks are usually public, and can be saved privately, shared only with specified people or groups, shared only inside certain networks , or another combination of public and private domains. The allowed people can usually view these bookmarks chronologically, by category or tags, or via a search engine.
What is Social Bookmarking? - http://en.wikipedia.org/wiki/Social_bookmarking Founded in late 2003, del.icio.us pioneered tagging and coined the term "social bookmarking".
Many educators already use Bookmarks or Favorites in their personal browsers to save Web sites they use frequently in class or at home.
But, what if you've saved a site on your home computer and want to find that Web site while you're at school? Or say you want to share your bookmarked sites on Edgar Allen Poe with other teachers? The typical bookmark/favorite system doesn't work for these scenarios.
The big advantage of social bookmarking is that allows individuals to reap and store the fruit of their own research, while enriching the knowledge and experience of others through sharing of bookmarks. This turns the entire online community into a willing army of researchers, creating a semantic web in which the relationships between objects are machine readable. This is important because it helps computers to arrange, search for and present information more efficiently.
Because tag-based systems have no standard set of keywords they can be subject to errors or ambiguity. Mistagging due to spelling errors, the use of tags that have multiple meanings, and the lack of hierarchical relationships between tags are problems that must be addressed for the long-term success of social bookmarking as a way of organizing the Web.
Social bookmarking is also susceptible to corruption that may be introduced by users with an axe to grind, or a product to promote. Spammers sometimes try to bookmark a page many times, or tag it with popular but irrelevant tags, hoping to fool viewers and influence their search engine rankings.
Scuttle Similar to BuddyMarks, but also can be installed on a local server (such as your district or school or even classroom) for further safety. Built for the K-12 classroom, the online version is cross-platform of course, but the local install is PC or Linux only (no Mac).
Edutagger - http://www.edutagger.com/ is another social bookmarking site created for k-12 education.
Connotea and CiteULike are aimed at academics and researchers and interface with certain databases and journals.
FURL and Delicious .com both have free registration, and easy pop-up saving forms. Delicious.com has a nice feature of suggesting tags, while FURL actually saves a (private) copy of the page, so you can see it even if the page disappears or changes.

3. track author and book updates
4. groups of students doing a classroom project sharing their bookmarks, a teacher subscribed to their rss feed to see the direction of their research. (FURL - teacher can review and comment on resources that are bookmarked)
5. resource teacher does a PD event with a group of teachers creates a shared del.icio.us account where teachers can post research and information bookmarks that they gather throughout the year. All members continuously benefit from this shared resource.
6. rate and review bookmarks to help with students decide on usefulness of resources
7. setup a group tag in order to share educational resources (IE. Dekita Exchange and on this wiki in Geocaching for Educators )
8. unintended learning through the discovery of resources and information shared by others through their bookmarks
9. Share links to current news items that relate to classroom discussions.
10. Examine the popularity of a web site that a student had listed and examine those who have tagged that resource in order to find new resources. (and perhaps unintended learning opportunities)
11. Share one del.icio.us account between a number of different subject specific educators or a school in order to share resources with each other. (see Willowdale Elementary School and District6
12. Share one del.icio.us account between a large number of educators across a school district that teach in diverse settings in order to create a broad and deep set of resources. (see Traverse City Area Public Schools for district wide social bookmarking)
13. Students bookmark on a subject before a lesson (as a reading exercise), then review those sites after the ‘talk and chalk’ part of the lesson.
14. Students bookmark sites during a lecture, then review during question time.
