From Kristen Nicole at Mashable: Wikipedia Paying Contributors?
Wikipedia has agreed to pay illustration contributors for their work towards the online encyclopedia. This is an unprecedented move, as wikipedia is based on volunteer work from contributors across the world. Contributors have not been compensated directly from Wikipedia’s foundation for work done on the resource site since its inception, and the very subject of the matter is a complicated one. How do you maintain a level of collaborative idealism for a self-regulated entity if people are being compensated for their work?
You don't. This is a huge mistake and one that will completely change the dynamics of Wikipedia. They just devalued everyone's contributions. Bad, bad move. Hard to believe they would do this over such a paltry sum of money.
I hadn't made my annual contribution yet, and won't be now.
