I made this same post like 5 months ago, but it is still pretty relevant. While there are some bad posts on the forum, I see a majority of posts being downvoted or given negative kudos.
Seeing as how all the recent ones are "-1" with 0 comments, it looks like someone just scrolled down and clicked the down arrow on all of them without even reading.
Why is this an issue?
I use Kudos to see what posts are interesting/valid, and if other people see a thread with "-1" they will just dismiss it a bad post and move on, not helping that person.
This might not be true, but again, this is my opinion and how I interpret it.
There ARE posts that deserve a downvote, but there are plenty of innocent, nice questions that get barraged with downvotes for no reason.
Not everyone is a script kiddie begging you to hack their friend's facebook. (although there has been an increase of those kind of posts)
