Take the analogy of doing the same in the offline world. You have a house, you have your stuff, some of which you keep inside your house and some in the garage. Would you rent a storage space to keep other people's stuff? You certainly wouldn't keep other people's stuff in your own garage to begin with, even if that stuff is "informational".
You see, there is a reason why Google is not in this business of bookmarking, nor do you see Facebook, Microsoft, Yahoo or anyone else. The browsers provide this as a basic service, so you can keep the URLs in history or bookmarks manager. The online world would be a really silly place if people in general would have to pay to keep the website URLs.
