Very interesting. Both of your posted examples of your own creativity and both are worlds away from the first thoughts that come to mind when the artisan archtype is mentioned.
Both of you mentioned creative pursuits that are for the most part, solitary pursuits. Indy even came right out and said that she prefers to avoid the social stuff if at all possible.
I'm the complete opposite. Outside of writing, I'm not particularly creative. Even writing to me is just story telling, and I'd much rather be telling stories at a party where it's much more fun than sitting behind a monitor. I'm the guy that lives for opportunities like open mike night at the comedy club. I love that kind of thing.
I can't live without social interaction. I thrive on the party atmosphere and I tend to brood if I'm forced to stay at home. Well, brood and freep anyway.
Call it a very strong hunch, but I'd bet body parts that introverts are EXTREMELY overrepresented here on FR, and that extroverts are very rare.
