I would simply be happy with constructive criticism from the post-promotion section. I added my plea for help as a part of selling your idea.
And yes, the key in criticism is not too attack when giving it and not to defend or deflect when receiving.
I love the old saying, " sticks and stones will break my bones, but words will never hurt me."
I get you, that's what it is all about. It should give us a good standard for sure. I don't mind so much about the upvotes right now, it's all about getting the feedback so you can continue to grow.
Good point about criticism, I'm going to copy that and edit it into my post if that is alright?
You have my permission.
