I don't know. And I don't think it's something we should define.
I like to think about our users, both audience and journalist, in terms of Twitter, Instagram, and Facebook. Twiiter didn't ask "what topics should our users tweet about?" but rather they said, "Here are a set of tools to communicate. Go for it!" And people have gone for it.
And yes, those services are free to the user. Indeed, that flood of information is free and it should be free: the vast majority of it is throw-away material. You get what you pay for.
Traditional media had a lock on the distribution of news. They decided what "news was fit to print." In the digital age, that lock on news distribution is gone. Now the audience can determine what news should be "printed" because on CrowdNews, they can buy it directly from the journalist. We are disintermediating the news industry.
So, our job at CrowdNews isn't to define the topics of news, but rather to build the tools and marketplace that journalists can use to report, find, and sell their work directly to their audience.
