I just discovered del.icio.us. Del.icio.us is a social bookmark manager. What’s that you say? Essentially a way for you to manage your bookmarks across any number of computers using a tagging metaphor like Flickr. And, even better, you can see what other people like that you like, etc.
I’ve added the last ten things I’ve tagged on del.icio.us to the right hand navigation bar of my website for fun.
