Have you ever wished that you were able to trade your proficiency with another? Often, as a designer, I have wished that I was a good developer. Able to go out and develop my web apps. At the end of the day, I suppose I can accomplish different things than a developer and just hire developers, but it sure would be nice. Or I could pick up a PHP book and learn.
