I personally feel that we don't need money-grubbers on mabination... If their posting incentive is money, I don't think they'll be contributing much.
Not always the case.
One can love their work and be in it for profit at the same time.
The biggest reason why Itchy failed to contribute was because there was no sense of pride over his "product". He didn't make it, he didn't help it become what it is, he just bought it with profit in mind.
Ever had a job? If you work, for example at an Ice Cream store, at first you just want the job for the money. Eventually, you'll come to hate any other ice cream store as you feel they are vastly inferior to the one you work at. Its a sense of pride in which you believe you have contributed to your store to help it become what it is, even though the end motive is still money.
