Given this post there is a comment saying:
"I am sorry to hear about your loss."
I flagged it on the day being posted as not constructive (as I can't see in what way this will help any reader that gets to OP by google and reading the comment).
Today I noticed it got declined and the comment now is even highly upvoted (pushing useful comments even away as long you don't expand the list of comments.)
So I really can't see why my flag was inappropiate. I even see more informations given in comments like "wow, great answer +1" which are all over forbidden.
But here someone without knowledge about what's the correct answer gets at least an indication of views about its contents.
While I aggree this is not objective in contrast to the value of SE's voting systems, it anyway will still never be of less value than a comment like the one cited above. So what rule makes that comment valuable and even determined by upvotes highly usefull?
