What kind of quality do you expect for 2 dolllars?
For a researched article the reward should be way higher to compensate for the time invested in the article.
I normally write articles of 500 words for 10 dollars. Could do it for 7 dollars.
Im not expecting a higher quality article at the moment, because my site is few days old child, and I needed content for it, to give it some power. I have 15 Question and what you need to do is find the answer of these question and write it in your words and 2-3 lines. That is really a very simple task i think, it will not take your 10 min
