"Furl is a free service that saves a personal copy of any page you find on the Web, and lets you find it again instantly by searching your archive of pages. It's your Personal Web."
"Furl anything you want with a single click. Each member gets a 5-gigabyte personal archive, large enough to store tens of thousands of pages."Its been a great help, specially when archiving Philippines news articles. I now have the leisure to bookmark the articles I want to read without fearing it will disappear in a week or so.
Of course, if the company that owns Furl folds, all the saved bookmarks will disappear so one should back-up the important links you really want to preserve.
