Ok I know there are many many question about it, and I have no problem with closing this one if someone can guide me to the answer I am looking for.
Sometimes, I like to give sympathy-upvotes myself : if I see an answer in minus that has no reason at all to be in minus as far as I am concerned, I upvote. I must admit I wouldn't upvote it when it was 0.
Eg: s.o. asks something very trivial, like a syntax issue :
'why is 'select * where a > 0 from table'.` not working?
Then I don't even read the answers. A '-1' however stands out, and when it's correct
'you should check your syntax, where clause comes last''
I undo than the -1 because there's no need for it.
Maybe a bad example , but in cases where I think the answer doesnot deserve a minus, but in my opinion neither qualifies for an upvote, what should i do?
