As I have researched and tried to learn how SE works by reading different comments, answers, questions and blog posts, I have come to the conclusion that SE is interested in becoming the Q/A site providing the highest quality Q/A pairs.
For this to be possible, there needs to be some way for the content creators to easily see how they can improve their content based on some easily digestible data (feedback) provided to them.
My first thought was that the voting functionality is the data I should trust on to decide if my question or answer is of high enough quality. But after researching the voting functionality and its underlying use-case this seems not to be the case. I have received feedback suggesting that the voting functionality is mainly there to improve visibility of content which already is considered to have a high enough level of quality.
The voting functionality also has multiple different meanings and on top of that is different between Meta and main sites. So I cannot know which meaning the downvote actually has.
Then I thought about comments. Maybe feedback on how to improve my content would be provided via this channel. This actually wouldn’t be any measurable evidence, as words are based on opinions of the writer. Also, by further research, I have come to the conclusion that providing feedback on how to improve the content is not seen as necessary here.
One answer is suggesting the Question Wizard. While i see the intend and usefulness of the tool to improve the initial Question. It is not helping to improve the Quality of the Question, not to mention the answer, after it was created. Furthermore it is not a metric of quality, it merely is a tool to help me understand what the community perceives to be a question of high enough quality.
It also suggests that after submission i can only "Hope for the best". I believe that this is not a good approach at all. If i just hope and act randomly without any measureable evidence no quality is achieved. You can see that if you observe AI Systems which are provided with to less Data and Feedback. They act randomly but never evolve in any meaningful way.
As those are the only two metrics I can see in an obvious way, I now ask myself: On which data should I base my actions on how to improve my content?
