This is a fantasic new tool. I have been using it for about 2days, and it has sooo much data it makes my head spin. You can get more information at: http://www.seomoz.org/linkscape
Nice tool, I just tried it. What else it does beside Analyzing the website? Does it tell you what steps you should take to improve your site ranking or something? If yes, let me know 'cuz I couldn't find that step...
