> I’m of the belief that HN would benefit from showing a user’s up-votes and down-votes
Posting history of any account is already visible. That's already a lot of transparency.
Having individual account vote histories visible won't add any benefit, but will increase ad hominem attacks within discussions, and will also increase hive-mind type voting.
Hacker News is just a discussion forum. This isn't real life. The focus should be on the discussion more than the people-there's not much in the way of profiles. It's weird to ask more of a discussion forum than a government election process which actually does matter.
> Also limit down votes per day
Posts can already only be downvoted for a limited duration. You also can't downvote until you have 500 points.
If you require spending points downvoting, it simply further incentivizes point harvesting or spending all day on HN so you can have more power, which only drives non-genuine activity.
I think personally once you reach 1000 points a star should be displayed instead of the score.
