How do these sites do it? You answer 4-10 questions about yourself. Or in this case you only put in your name, and wa-la, it tells you all about you. Like below, it's very close to to me. How does it know from typing in 'Angel'. Weird. Enjoy!

You are usually the best at everything ... you strive for perfection. You are confident, authoritative, and aggressive. You have the classic "Type A" personality. You are very intuitive and wise. You understand the world better than most people. You also have a very active imagination. You often get carried away with your thoughts. You are prone to a little paranoia and jealousy. You sometimes go overboard in interpreting signals. You are deeply philosophical and thoughtful. You tend to analyze every aspect of your life. You are intuitive, brilliant, and quite introverted. You value your time alone. Often times, you are grumpy with other people. You don't appreciate them trying to interfere in your affairs. You are friendly, charming, and warm. You get along with almost everyone. You work hard not to rock the boat. Your easy going attitude brings people together. At times, you can be a little flaky and irresponsible. But for the important things, you pull it together. You are relaxed, chill, and very likely to go with the flow. You are light hearted and accepting. You don't get worked up easily.
