Why not asker points and level in yahoo answer?

I observe and found that there are always lot of inappropriate question published in yahoo answer. Which I think no proper use. To be sincere in asking a question there is the need to educate asker by yahoo answer team.

Secondly, most of the asker do not select the best answer even after 4 days. This causes the question homeless and the effort of people who answering the question become meaningless, and the process of voting started. But as the point of voting is 1 many people do not like to invest their time in voting. In sense it decreases the value of yahoo answer. So I think there is a need to develop a system by yahoo not to allow such asker if they do not choose their best answer in time or if pending.

Third is there should be a provision of points to best asker and a level of asker which is going on for answering. I think this process will improve the yahoo answer and will help to attract more and more people.

Fourth is the question should be in short form, a minimum space for a question to be allow so that the asker give effort to ask a question carefully.

So, is there any need to allow a provision of points and level for asker by the yahoo answer team?
