And they don't exist for article submissions, which is problematic for all the same reasons I listed in the blog entry.
that suggests they are overutilized elsewhere and work pretty well here, I am not adverse to opposing viewpoints, I just dont want to see plainly dumb comments, if you overuse it, then it loses meaning.
(taking this thread as a test data, while I dont agree with a lot of what people have said, I wouldnt have downvoted any)
There aren't article downvotes-- but there doesn't seem to be a need for them. The moderators kill stories that are plainly inappropriate, and the ranking algorithm makes it difficult for things to reach the front page without a decent number of upvotes in a short period of time.
My point is: this is an interesting and subtle topic, and it might be in your best interest to study it in some detail, rather than just glancing superficially at what others are doing and forming conclusions thereupon.
It sounds like you didn't actually understand the dynamics of the HN community. You sound silly insisting your initial impression is even partially right, when the whole community is telling you the opposite. (This applies only to posts, of course. Downvotes still don't exist for stories themselves, outside of flagging.)
As for your assertion that not disclosing the karma threshold for downvoting is 'bizarre', I'd argue it's useful not to provide an exact number. Enough video games have 'achievements' listed out for people to obtain... I'd rather have people participate honestly than just to gain more 'abilities'.
