I can't answer your questions, as I'm also new to Steemit,
but what can I recommend is to ask these questions in the posts of Steemit developers, or people who are in charge. They probably just didn't notice your post, as there are lots of posts here.
Regarding monetization - I think you can allow "promoted" debates. If your app is successful this can pay for the work done
Thanks dear, I will try to join any developer forum on steemit.
You are welcome!
