For me it's because you get to produce something really nice, artistic, more or less to your specification but always with the hidden surprises in the wood, relatively quickly start to finish (try that working for a defense contractor), without some unqualified moron making negative, subjective assessments. You and your relative sense of perfection (and perhaps a customer) are the arbiters. Where else can you get all that? What's not to love? Oh, and I agree with artistwood - you meet great people, some of which are funny as heck (e.g., I laughed until I almost wet my pants looking at the picture of the pre-photoshopped sponge-Bob pen holder in the recent contest)...
