Social bookmarking

Social bookmarking is a mechanism based on grading (e.g. through a ‘like’ mechanism by using the classification system of stars or tagging) content items available on the network by large groups of Internet users. Thanks to labeling those most valuable (or interesting for a given user category) content, other Internet users can access more effectively resources they are looking for.  Social bookmarking is very important in the self-improvement of one’s skills based on the open content mechanisms.
