Helium lets you write articles and lets others post comments to your articles. By doing this you get to hear what others think of your opinion and your writing. Write about something controversial and watch the comments come in.



If you're a non-profit organization, you can use this service too. Write about what your organization is doing and what they stand for. Watch people, for and against you opinion, fight it out in your comments section.

The best part about Helium is that if your articles are any good and lots of people vote for them, you could get paid. If you want to donate your money to a charity, they'll help you do that too.
