I have only been directed to this thread this morning. Before reading this I had no idea what "acceptance rate" meant - I had assumed that StackOverflowStack Overflow was telling me how many of my answers had been accepted by others,others; I had no idea it meant how many questions I had accepted answers to.
So when someone asked "Why the low acceptance rate" on one of my questions I had no idea what they were talking about. If they had not done so I would still be in the dark.
But there is a really simply solution!
When someone starts to ask a new question, if their acceptance rate is below X% have the website show a red warning message above the Title input which states:
Warning: You have accepted answers to only Y% of your questions, this may deter people from offering answers.
