I agree with your ideas and we should be having more often conversation reviewing ways to improve the experience of people here.
I would just add to the discussion the importance that this platform should be doing in terms of reinforcing the message to push good quality content and not promoting quantity without any substance.
I see a lot of repeating posts that in the end don't add any value and are just there to have quantity in order to get their daily votes. This also includes the 'spam' of some apps that post in your name to promote their services using your rating, activities or information and sometimes offer upvotes to do that.
