Social bookmarks are links saved on Web sites that allow users to annotate, tag, and share them with other users.

Example: Pinboard
 
To evaluate the content on a social bookmarking site, look for these clues:

• The purpose of the bookmarking site. 

• Bookmarks of interest to you have also been bookmarked by others.


• The quality of the bookmarked item. Determining this will be the same as determining the quality of any Web resource.


• The individual who bookmarked the site has expertise on the topic. This often cannot be determined, as users tend to employ nicknames as their identities.
