This is an almost exact duplicate of this question, which did not receive any answer. I find the fact that this problem is the same as 5 years ago very odd.
I participate in this stack for more or less a year and I notice a very little recourse to upvotes. There are many questions that are well formatted (for instance, proper species identification questions) which are not upvoted at all. Sometimes, even questions with answers are not upvoted - see this one with an answer from Remi.b and this one that has two answers and only one upvote, which is mine. I really do not understand this behaviour - either the question is bad, and as such it is not answered, downvoted etc, or it is good and as such it deserves an upvote, and when possible an answer.
I find that this lack of reward through upvotes is one of the causes of the poor participation of users to this site.
Why is that? Do you agree with my analysis?
