Please, visit [my][1] question. You will see the post has 3 downvotes and one of the answer got 3 up-votes. Moreover, the answer that got 3 votes is a mere try, not complete answer. On The other hand my complete answer (right or wrong) got no vote, or any constructive, real feedback. Would anyone be kind enough to explain this "counter-intuitive" phenomenon ? Thanks.
