Yahoo finally released toolbar / button for Internet Explorer. This software is in beta and works like a charm. There are similarities between this version and the recently released Firefox 3 beta extension -- including features such as the del.icio.us Sidebar and Toolbar for quick access to your bookmarks. The extension works on IE 6, IE 7 and IE 8 beta for both XP and Vista. Check out the del.icio.us blog for more information.
