First off, I highly appreciate the feedback. This is exactly what I'm looking for.

What you need is an active community to start collaborating on more in-depth sub-guides on the wiki, otherwise you'll need to dump hundreds of hours into research.

I plan to cover just the basics to start (although I will eventually be expanding into more advanced subjects) so I hope it won't take too much research. I also want to take guides that have already been written and are well-formatted and supply those as additional resources, as I've done in the Grooming article. No point in covering territory that's already been explored.

I totally agree with your assessments for a platform. You're right, on SaidIt and Ruqqus I'm having a hard time finding people who would be interested, even though I find the culture generally better than Reddit. I think 4chan could be very receptive, but unfortunately they do tend to ban self-improvement threads. For now I'll stick mainly to Reddit and stay on the less swamped subs.

Btw, would you be interested in contributing to this or sharing it?
