So once again I am off to Demo. This year, 70 companies -- mostly startups -- will use the conference to present to VCs new takes on technology. For the purpose of full disclosure, let me say that Demo is an event put on by IDG, the parent company of InfoWorld.

If there is a theme, a single blood type, if you will, pulsing through startups' veins at this year's Demo, it is user-created content. And on the bleeding edge of that technology is a company called Helium, which went live in October and will announce its Helium Debate technology at the conference.

As opposed to Wikipedia, which uses citizen editors to perfect a single article, Helium offers a forum for experts to submit articles for peer review.

Using a unique algorithm, articles on a single topic are compared side by side, and reviewers rate them. If there are 20 articles, it does not mean that Article A will be compared with the other 19. But, if Article A is better than Article B, and Article B is better than Article C, the system assumes Article A is also better than Article C. Top-rated articles go to the top, offering the reader a variety of perspectives, as well as additional information. Lower-rated articles go to the bottom.

Helium Debate will bring this technology to discussion topics, ranging from whether troop-level increases in Iraq make sense to whether declawing your cat is cruel.
