Sanjeev, there is a provision for Best Answer Award in the Q&A section, and it was very much active, but owing to very less participation and almost no quality and relevant questions being asked, the award has been discontinued. I myself have one a few when it was active!!

Sanjeev, your idea is good but it has its own disadvantage also like if best answer selected then others will not answer for that thread. So i think admin will not accept this. :)
