Hi John,
For which question you are talking about. In general what Seema told about keeping a senior person as a Judge to say whether it is right answer or wrong answer. If that is the case even I can take that role, but everyone may not be well versed with some topics.
For example, for the question by Mr.Thiru, I was not knowing correct or much about that topic, hence I need to keep quiet. Similarly when there is a question on different topics, for which the appointed judge could not answer or not knowing the answer, then what will be the situation, and who can declare the winner.
That is why we are telling the person who is posting the question is the best person to judge the answer and declare the winner. If the answer given by the person who posted by the question, then whoever knows well , can point out the mistake and can give the correct answer. There stops that topic for further discussion.
This my opinion.
If you differ from this, please put in your views.
