Asking how to monetize something like GameFAQs or Wikia feels like how do you monetize friends sharing tips and talking about common passions with each other? Why does that need to be monetized? Some dude figures out left-right-B-A-B-B and posts it to a message board and doesn't need to be paid for it.
I guess another example is my favorite podcast, Iron Culture. Both the podcast and the YouTube channel don't accept sponsorships and lose money, but the hosts are both coaches, one is a scientist, one runs a small supplement company and hosts a History channel YouTube show, and they make their money from that. Recording themselves talking about their research and interests that they'd be talking about with each other anyway doesn't need to be its own full-time job.
Granted, I don't know what this means for real journalism that involves running beats, traveling, long-form investigations, all of which are definitely full-time jobs and not something you just want people doing as a hobby they record themselves during. But a lot of "good content" is not journalism. It's just people recording their thoughts and findings while doing a hobby they love in a way that they would have done for free in the past while still having a regular job, but for whatever reason, that's no longer good enough.
