Social bookmarking tools

Social bookmarking tools offer some distinct advantages over the traditional terminal based variety. First, there is the obvious "portability factor" (which raises the question: I assume Del.ic.ious offers hand-held access. True?). Second, and more significantly, the "folksonomy" factor expodentially expands access to potentially useful sites. Like other aspects of WEB 2.0, this feature facilitates information sharing among like-minded people who, otherwise, would not likely to connect. I can see the potential for using this tool as a current awareness opportunity. On the down side, there is the ever-present issue of "information security". One can gain much information on an individual by the types of sites he or she bookmarks. As with other Internet based resurces, one must use the standard precautionary measures. It is a fact of life that greater access to information also includes greater security issues. Thatis the reality we live with, unfortunately.
