HeliumKnowledge is an Internet site that allows you to answer people's
questions.
You'll be paid according to the number
of surfers reading your answer.
When you reach the minimum of 25$, the sum will be sent to your home.
When answering someone's
question, you must grade two other writers' answers. After you've done that, your answer will be published.
When other people will write an answer to the question, they'll grade your answer.
The highest your answer is graded, more people will watch it, which means more money made by you.
Therefore, it is extremely important to be precise and detailed when writing it.
An answer could be one word or even a Hyperlink. That, of course, won't earn high grades.
You can also write
questions in the site. Me myself haven't got to the 25$ limit (not even closer), nevertheless the site seems to be trustworthy.
Enjoy, earn some money, and maybe even you'll get to learn something new!
