I would get amused to see the questions and also feel that I should answer them which are best known to find an expression of knowledge and consensus mostly ,Some times I feel when the questioner fails to rate any thing whether it was useful or not useful ,I feel discouraged and I avoid non responsive questioners and dissuaded not to answer any more . Had the questioner are prompt with rating and awarding B A ,I would feel better encouraged .
