I have noted that several questions have answers and sometimes multiple answers but no votes either up or down. It seems to me that if a question is worth your time and effort it should also warrant a vote.
addendum: Since my original post several people have responded in a manner which leaves no doubt that it has inflamed them. That surely was not my intention, some responses came from someone whom I am sure have not answered any of my questions. I am not proposing that people vote on all questions, I certainly do not.
Correct me if I'm wrong, but this is my impression:
an up vote indicates that you feel the question is proper for the site, and a down vote is not.
If you take enough time to answer a question it seems evident to me that you feel it is cogent, otherwise why waste your time with an answer. And if you feel you are qualified to answer the question then you should be qualified to judge the value of that question.
I have always been under the impression that a comment was something that you felt the author needed to know but was less than an answer. for instance that the question did not properly fit the site, or as Fredsbend commented on one of my questions that it was so inflammatory that it had caused splits in Churches, and I immediately withdrew the question.
I for one take all answers and comments seriously, otherwise I would not bother to ask them. I know I ask a lot of questions, but these questions have occurred to me over a long time of studying the Bible.
