Anyone have an opinion on helium.com and the way answering questions works?

I can't figure it out. I thought it was similar to yahoo answers and I still think it might be, but apparently you get paid for answering questions on it - something to do with adclicks, but doesn't make sense to me. I tried to ask on the site but haven't got an answer that make much sense to me yet. I also really can't see how they can make money from folk writing answers all the time!

Helium is a community of people sharing knowledge. The Helium four-prong formula is: "Reading, writing, rating and reward."





Reading: Whether you are researching what movie to see or what car to buy, it’s always great to hear from many different people to get the whole story. At Helium, many people can write on a given topic providing readers with insight gained from multiple points of view.





Writing: At Helium, anyone can write on a wide variety of topics, everything from parenting to personal finance, and they are paid a portion of the advertising revenue earned by their articles. The earnings are into perpetuity so if you write 100 articles, you will continue to get paid for those articles month after month as long as they continue to generate ad revenue.





Rating: Helium uses the power of people to organize the chaos. This is accomplished by giving writers the opportunity to rate other people's articles in an A vs. B fashion. This peer-reviewed rating system allows the best content to "float to the top" (Helium) so all the content is organized and easy to navigate.





Reward: The better your content, the higher your article ranking, the more page views your articles get, the more ad revenue you earn.





Good luck at Helium.
