Expanding on this idea, I think some key lead roles would be helpful. At the end of the day I think for something like this to be successful at least a few people would need to take charge of particular aspects of the project and from there things could become more diverse trickling down through the users. Some thoughts on those roles, thinking in terms of bare necessity as I see it.

Overall lead

• Someone who keeps track and contact with the other leads and replaces them if necessary.

Technical Lead

• Someone to provide data and analytics that will fuel the various types of content produced. Basically tasked with making things as accurate as possible, while also highlighting the strongest points that we'd want to promote.

Marketing Lead

• Someone that decides and leads the charge of what's going to get posted where and when. Able to provide the community with resources that are created and primarily tasked with having a strategy as to whom to target and with what etc.

Creative Lead(Visual)

• Someone in charge of visual branding, aesthetics and consistency. (I'd be willing to fill this role if no one better suited is interested) Primary role would be establishing the style of the visuals, recruiting community assistance on the design front and keeping that visual messaging consistent through providing guidelines to others. Would need to work with tech lead to consolidate the message.

Creative Lead(Writing)

• Basically the same thing as the visual creative lead only with the writing aspect for articles, blog posts, or whatever other written forms of content that would be generated. Would also work closely with tech and visual creative lead to have a consistent and consolidated message.

As @edje suggested I think the best idea would be to organize this in a discord, start with these roles and let everything else trickle down from there.
