Social Bookmarking

Social Bookmarking gives us ways to organize, store and access informative sites for professionals and amateurs. The opportunity to add them to information you want to share with students, friends or family allows everyone access in different venues.
Teachers can use them to direct students to particular sites by adding the bookmark to an assignment. We can add them to our favorites, tag them with a title to find them again easily, and share them with anyone we want to.
Bookmarks can be tracked to know how many others are using ours or adding them to theirs. They can be a useful tool to use the bookmarks of others and not just our own. Some bookmarks can be accessed from any computer, so you have the ability to access your information, no matter where you are. You don’t have to be on the same computer every time.
People have the opportunity to make comments about the usefulness, truthfulness, or accountability of different bookmarks. Some companies automatically delete sites that are no longer available. They may remove sites that are offensive rather than containing information that is related to the subject.
If we don’t use enough tags to promote use by others, we may be limiting access to useful pages on the net, and some pages are printable. If we are looking for horses, dogs, equations, or whatever, the major sites will be accessed easily, but may not contain the information we want because of the ‘tag’ we used.
By using bookmarks we have an easier way to access the same useful information more than once, and not losing it forever because we didn’t make a note of the address.
