One week ago Del.Icio.Us released their new beta extension for Internet Explorer (6.0,7.0 and 8.0). I am using the IE extension button for a while at work & home to tag and group my Internet favorites. To me this is one of best tools you should have when using Internet. In the past I struggled many times with different kind of favorites folders and sync those with Firefox and vise-versa. The features and look and feel were already available for Firefox and now finally with IE.
