Social Bookmarking

I define social bookmarking as a place to keep the favorite websites that you have visited for easier access.  Also with social bookmarking other people can see the websites that you bookmarked.  It is a public website to bookmark.  Social bookmarking could help me as a student to save websites that I need to write papers or for projects.  It could help me as a teacher by saving websites for good teaching lesson plans or activities.  I think social bookmarking in a good idea because it also gives other people help when trying to find certain websites. We can go to other peoples bookmarked sites and get a look at their ideas as help for whatever we need help with.
