Have you realized? del.icio.us got a new URI: http://delicious.com. Johannes Meinecke pointed out the new toolbar for Internet Explorer which is quite an improvement to the previously offered buttons.
Since I use multiple machines for development at work and university but also at home, delicious became one of my favorite tools for managing bookmarks. The best feature coming with the new toolbar is definitely the complete integration into the browser. By selecting one of the bookmarks you can directly change it’s properties without browsing to the delicious site.
