Forget putting bookmarks in your web browser anymore. If you're like me, you'll probably rarely use those bookmarks. I have so many and I am too lazy to create folders, so I have so many booksmarks it overwhelms me and I immediately jump to a search engine instead. Now you post all your bookmarks to del.icio.us. Another great example of Web 2.0, del.icio.us allows you to tag all your bookmarks with categories, so you don't have the hassle of creating folders. Plus you can access your del.icio.us bookmarks from any computer and you can create a network of users with similar bookmarks as a way to find other interesting sites.
