As someone who ran a rather large and supportive Facebook Community group (self-help journaling space) I can attest to what's in this article. Great suggestions! :)
I was thinking about joining a group, though I'm rethinking now.
Full support for expanding the conversation across the platforms and articles!
Something I've found very interesting around stats is the amount of people stated as being here, yet not seeing any articles or accounts that crest 10k or even much higher on followers, Claps.
No assessment on it, just an observation. Still as you stated on the other response Medium is all about that secrecy.
