No matter whether you are at home or at work you can access your bookmarks making this a wonderful tool
You don't have to use the same computer which is great for a class assignment as the reality is they don't get to use the same computer each time. You can tag sites and more sites added as you find them. This is a time saver for the student as they have access to relevant sites without spending time looking for the sites and wasting time.
For me personally I can see its uses particularly for hobbies I am interested it. I can bookmark all my favourite sites and have them at my fingertips
