After using SO, for sometimes, I realize that I got some problems.
Zen masters fighting each other on one of my question. Every side have their own arguments and everybody seem right. Frankly, this confuses me: How can I choose somebody's answer where I don't know the right answer?
Therefore I would like to propose the feature I choose this, because for a user who asked. So at least he/she can explain why he has chosen the particular answer. Maybe it's silly, but as somebody who's getting helps from others' answers, I would like to know everybody get what they deserve. Usually in this kind of situation, I just upvote every good answer and check the one I think the right one.
Second feature:
Every hot question always got plenty answers and comments. If a debate starts among the answerers, it could become hectic. Right now there is only the possibility to sort answers based on oldest, newest votest. So, is it possible to make a new sort based on timeline what make comment and answer collide. I believe it will be more easy to read. This feature can only be seen by the person who creates the question, or also for public.
