10 cents per word? Damn man count me in for writing! That aside i think you would get better results with Adwords or backlinking services.
I'm not 100% sure. Maybe short term it would mean more income, but in the end (let's say 5 years), I think I can get more from real, good content and keep investing in daily fresh articles. $0,10 per word is an estimate, but maybe it's too much. Not sure how much it costs for top quality, researched content.
