social bookmarking

Social bookmarking allows consumers to share their favorite bookmarks, Web sites, or content with others by submitting links to a public or semi-public forum. On social bookmarking sites (see below) consumers can browse (and comment on) links and content submitted by others, giving greater exposure to the most frequently shared items. As publishers and portals add these features to their content and in turn, those preferences can be tied to a user's profile page, it becomes one more way that users can express their interests to their peers.
