I also think that nature of many people here is not only to duplicate, but to improve on something and attempt to make the next one better. Coming up with a decent gallery and then duplicating it 1000 times is fairly mechanical, and I suspect the laws of diminishing returns will come into play pretty quickly on this concept.
While it is to your advantage (always) to sub out work when you can afford it and when the work can be done sucessfully (and at a profit to you) by a third party, for the most part people here have more time than loose money, and more desire to do thing themselves and develop ideas on the go rather than sitting back and supervising others.
Perhaps as a result many people where will remain small to medium players, but not everyone is destined for greatness and a 20 person staff in the office.
