Wouldn't a "Reputation per Number of Posts" stat on our profiles, and a possible badge for some minimum amount of the same, discourage low-quality and/or spam posts?
The reason I ask for this is that in my admittedly little experience on this site, I have come across a few high Rep users who seem to be prone to posting hasty answers.
The penalty for a post which simply did not happen to be well-recieved is not much either- for every upvote we receive $10$ Reputation, whereas for every post that did not receive any attention, the denominator will increase by just $1$. This means that we would not be discouraging users from posting good answers or questions that they aren't completely sure of.
However, this might incentivise high-quality answers as well as questions. Of course, for the proposed badge, it is necessary that some minimum Reputation be a pre-requisite, as it is much easier for a user with $1$ post which got, say, $10$ upvotes, to gain a $100$ Rep per Post, compared to a user with a thousand posts.
So, why don't we do this? Am I missing any negative implication? What does the community here think of this?
