Answer to Question 2
For many Web surfers, key challenges are finding information and finding it again at a later time; hence, people often keep long lists of bookmarks to sites they find interesting or visit frequently. Although this is useful for an individual, he or she may miss a plethora of other, related, and potentially interesting Web sites. Social bookmarking helps to address this by allowing users to share Internet bookmarks and to create categorization systems (referred to as folksonomies). As more people participate in social bookmarking, the value for each user grows as the bookmarks become more complete and more relevant to each user. Widely used public social bookmarking tools include reddit and Delicious. For organizations, social bookmarking can be extremely valuable for knowledge management and harnessing the collective intelligence of employees. Using enterprise-oriented social bookmarking tools, it is easy to map islands of knowledge within an organization, thus helping to easily find experts on a given topic.
