Yes I do seriously believe that. Why else would you think I'm supporting it, then?
Do you seriously believe introducing only the positive ratings would've improved the quality of posting?
The positive only rating system worked and works in many forums. It is quite popular. It's implemented on all major forum software, and used in a lot of different communities. So I consider it proven to be good enough.
The positive only rating system leads to better posts, as it is visible in other communities.
The negative rating system implemented here lead to a lot of hating and agressive postings and bans. Saying the positive only rating system would create that, does not make much sense. I've seen the original gamedev system create a lot of chaos, too. It was not perfect, no solution to that.
What both systems have in common, is, they're good enough. They're a bit different, but serve the purpose of promoting good content good enough. Both are not perfect.
Those who think that it will fail in THIS very community think this comunity to behave different than others. Which simply is not true. We have the same useless fights (this on included), the same Ego-wars, the same ranting, trolling, banning. There's nothing special in the way this community behaves.
And this is the reason i seriously believe, the positive only rating system is good enough. Not better, but not worse, than the negative rating system.
Happy now, MikeP? (not with the content, of course, just with the way I've written it)
