Fix HN by tying karma to upvotes.
https://news.ycombinator.com/item?id=3842554Both HN Articles and comments have been gradually slipping in quality. I think this is probably inescapable as more users with less discerning tastes and attitudes come on board.
However I think the slide towards a reddit style board can be slowed significantly by reducing the influence of new and less appreciated users. By giving long term HN users with high karma (ie. not me, but the people who made HN great) more up-vote power and newer members and those with lower karma less up-vote power.
The current system allows high karma users to down vote, but this power is nullified when everyone has the ability to up-vote. For example you could have one dubious article or comment upvoted 100 times by users with 0 karma.
I propose halving up-votes for those with low karma and doubling the up-votes for those with high karma. This way you retain the influence of original members, and you further incentivise new members to make meaningful comments and strive for higher karma.
EDIT: benologist makes a good point that high karma might just represent a lot of submissions and not quality posts. Perhaps then the up-voting could be tied to karma avg. This was you incentivise posting higher quality comments and articles.
