I think the key is to try to create a single open community - to try to break down hierarchy and entice more users into viewing sc as “theirs”. Just today a user used the language “I hope it will be implemented” for a method - perhaps they didn’t understand that they could participate directly in its implementation!
Another thought - I have female and non-binary friends on Mastadon who follow sc related tags - maybe some kind of outreach from this forum/dev-community ought to happen on social media?
