Because people will assume small replies are being made not for the sake of dialog but to increase post count.
I'd rather see Down Rep
removed and keep the Up Rep
system. Down Repping a post could still make the "Low Rated" words appear on the post itself but not directly effect the posters Rep. Thus making posts that have the communities disagreement(Or what not) still be highlighted without anyone feeling like they are being hated/bullied/etc.
Just a though. -_^
Speaking personally again, I'd rather get rid of voting systems altogether on posts. Seeing as how people feel like they're being harassed by a stream of down votes, I'd rather force the downraters to express their disapproval through words and not some -/+ buttons. That way, they'd have to choose their words and think about why they are disapproving something instead hiding anonymously or just letting a temporary flash of emotion get the better of them. As you know, one of the problems in a text-based medium like a forum is that we can't see the other person's body language, hear the tone of their voice, etc. so we can't tell if they are being serious, joking, or whatnot and a lot of misunderstandings arise and downvotes follow :/
Ignore functionality is important. Right now the problem is GOG combines ignore and report into the same functionality. Once they're disentangled I think everyone will calm down.
Tying ignore and rep / bragging rights together was a bad idea. But we do need a way to not see posts we don't want to see. This is standard forum functionality, as well as standard RL social functionality. It's something that GOG needs to have.
