Positive rep serves a good purpose, its a way of saying "good post"/"+1"/"I agree" without having to do a full post, and also for supporting good contributors to the site and all that kind of thing. I honestly think positive rep system is great. No one likes seeing 1 line "Good post +1" posts, but at the same time its great to have a way to say that without just spamming the crap out of the page.
Negative rep however is the dumbest system in the world. It literally gives you the option of saying "your post is shit" without giving any valid reason and or legitimate arguments as to why, and no real way to reply to the negative rep either without just randomly negative repping back (abuse of which the site's head admin is literally the most liberal abuser of, despite complaining about everyone elses "abuse" of the system).
For example, rather than neg rep, imagine the comments in neg rep as posts which start with "You post sucks, -one line reason which is often personally insulting-". There's no WAY any posts like this would EVER be allowed on any forum, they're non-contributing and don't add ANYTHING to ANY discussion, it's just a way of saying "you're a dickhead" and the system 100% promotes you doing it (except of course to certain people, lol). There's no other purpose for it other than to say "Your posts sucks" in like 20 characters.
If someone disagrees with you/your post or whatever, they should have to come up with and put down in words a decent reason so as to have a discussion on the topic. The neg rep system promotes the opposite in a way more hostile way and has led to some of, if not the most heated arguments/situations where girly community members get upset we've had on this site from the beginning.
edit: I don't understand why people are promoting this idea of "you should be able to comment on a thread without making a full post". That is literally just promoting poor posting quality and dragging down the site as a whole. If you call it "neutral" rather than "negative" it changes absolutely nothing. There should really ONLY be positive as a way to reinforce good posts without spamming up the forums, anything else and you should have to have a decent argument, not just say "no i disagree" in a comment without any thought out response. Giving the ability to downrep without comments more or less does the same thing but even worse. I just get a "Your post is shit" with no reason as to why/how at all and it's completely legitimate by the sites rules and nothing i can do to respond other than post a shitty "HEY **** YOUR REP EXPLAIN YOURSELF" reply or the classic "HAVE SOME DOWNREP BACK HAHA TAKE THAT!
