I like to save the URLs of sites or pages I might need in the future. Because I have had to change computers from work to home and because I’ve had computers crash and die,I like to keep my bookmarks in the cloud,that is,I like to use web applications to save my bookmarks,rather than save them in my browser. To do that,I mostly use Diigo,which I also backup to delicious,(just in case either fails).
