Helium Raises $17M This Year To Compete With About.com

Helium is a user generated editorial site filled with general-information and how-to articles.
The best articles are voted to the top by the community, who recieve related articles and select which one is best (this avoids the Digg power user model)
Helium has ammased 130,000 writers who have written 1.2 million articles (only 10,000 regularlly active)
Writers get a split of ad revenues on their pages, which averages a $2 payout for every thousand pageviews.
This past week they raqised another $2M to put their total funding for the year up to $17M from hedge funds and wealthy angels.
Helium users making the most money are fulfilling requests @ the marketplace, which pays users between 30 and 300 dollars from websites looking for content.
Traffic is rather bare compared to About.com. They average around 900K pageviews.
