Yahoo Answers needs the ability for the question asker to mark a 'great answer'?

Don't you agree? How many times have you answered a question first and someone comes with the exact same answer and get the 'best answer' for it. Or how many questions have you asked where 2 or more people have had excellent well-written answers and you can only award one of them with the 'best answer'.

Very infrequently, it needs a troll button, with any user getting above a certain amount of clicks losing their account.

Rarely. Because most of my answers are harsh and people don't like to mirror that unless they were trying to irritate me.

BA, Best Answer is sufficient. Use comment box to thank other answerers.
