RE: Now you can see the numbers.

So as I understand it at a glance, as the SF niche owner you should be looking to recruit people with expertise and subject-based writing skill to participate in that niche, right?

Yes, that is correct. I prefer to cast a wider net and just invite people to Narrative because it's a platform with a ton of potential for many niches.

So tell me why I ought to come and start generating content for you.

That's a great question, but you wouldn't be generating content for me. You'd be generating it for your audience. But there are a ton of reasons why you might be interested.

For starters, 85% of the generated rewards go to content creators, niche owners, moderators, and other community members. 60% go to content creators.
Beyond that, there is a growing community of great spec-fic writers forming there. Just take a look and see if you might fit in.
Not long ago, the Spec-Fic niche hit the top 10 in terms of number of posts. That's fairly significant considering the specialized nature of the niche. Among the fiction writing niches, we've got some of the best engagement.
I'm considered by a good number of content creators to be one of the best and most active niche owners (just ask around). I am not a passive niche owner. I am involved in the niche and take my responsibility to support the authors who pour blood, sweat, and tears into their craft as much as I can.
I am about to launch routine contests, writing prompts, and other exercises, with rewards.
Read my post on brand-building. It applies to fiction writers.

(Also, is that posted fiction or articles about SF or some of each?)

Yes. We have fiction writers, reviewers, other types of non-fiction writing about spec-fic, a podcaster, and poets publishing within our niche. If it's about speculative fiction, it's welcome.

I'd love to see you aboard. I go by @gardengnomepubs on Narrative.
