Here's another online personality test.  As with any of these types of things, you can take issue with some of the questions and how they are open to interpretation in different ways but it's still fun to see if it matches with how you see yourself.

You're a risk-taker, and you follow your passions. You're determined to take on the world and succeed on your own terms.  Whether in the arts, science, engineering, business, or politics, you fearlessly express your own vision of the world.  You're not afraid of a fight, and you're not afraid to bet your future on your own abilities.  If you find a job boring or stifling, you're already preparing your resume.  You believe in doing what you love, and you're not willing to settle for an ordinary life.

Generation X employees tend to be less motivated by promises of overtime pay and more motivated by personal satisfaction with their jobs. They want to grow in their jobs and learn new skills. They will change jobs often as they seek jobs that offers them both better benefits and more opportunity for professional growth as well as personal fulfillment.

Generation X employees want, and expect, their employers to hear what they have to say. They want to understand the “big picture” for the company and how this influences their employment and growth. They are creative thinkers, independent, results oriented and bring with them a healthy dose of skepticism.

So is there a grand unifier?  One characteristic that all generations share?  I'm not sure but I think it's a love of silver wristwatches.
