How does accepting an answer work?
I am sure this will cause some disagreement. Well I am first, just a student.
I saw many questions, with many very-similar answers. So the question may be "How do I throw an exception out in Java?" and then, 10 answers! And most answers are very similar.
I humbly suggest that there be a small flag symbol next to the question, something the asker can click to toggle. Like a small circle(greenlight?) , light-bulb symbol, or maybe smile face(walmart kind no fancies).
That way, maybe it will let a potential answer-person think - "OK, Bob is Happy with these answers. I will continue. " Or "Hmm, it looks like Kareem here is confused as he didn't put the symbol."
It is just a way to communicate without imposing on the answerer. If my noble friend Addy still wants to provide his own special version of answer, it is a free nation. And so it is still optional.
The underlying motivation is that multiple experts should not each be answering one question they know.
