del.icio.us is a website. I know, it looks weird, no www, no .com but it really is a website. It’s using .us instead of .com, and a subdomain of del so there’s no need for www. So all you have to do is enter in the word delicious with some stratigicly placed dots and you’re in. del.icio.us is a web based bookmarking, or favorites program. You can organized all your bookmarks online and share them with others. You can even automatically post them back to your website with some of their widgets and codes.
