I'm embarrassed to say that I have accidentally upvoted many times. This always happen on a particularly egregious comment that caused you to be distracted while clicking.

We should not remove down votes outright. I've seen a comment get downvoted to -4 because people didn't like the commentary, but then shoot back up to +10 when it was shown that they were correct after all.

…but if we remove downvotes, they will just stay at 1 instead of getting downvoted. Later they will still be able to shoot up. They will only get flagged if they are actively in the wrong spirit of the community. (spam, abuse, etc..)

The concept of "down" is conflated in people's minds in a way "up" isn't. It is used by people to mean either "I disagree" or "totally inappropriate". The first is not supposed to affect karma but the second is. If you simply replace "down" with "flag" it changes how people think about it.

As for accidental up-voting, moving the links so that there is separation would fix that.

Ah, ok, that makes a lot more sense. I was imagining removing comments that had been downvoted; not removing the link to downvote.

I generally agree with that, but it reminds me of another problem. The Karma number is now an ever-growing and meaningless figure. I think it should be harder to improve your karma as you get higher, and it should be easier to lose it. That it actually has a meaning.

ah.. Progressive taxation. You're a commie liberal aren't you. ;-) (don't worry, I am too)

Inflation may be a problem some day, but for now I think it's under control. The leader board is still at a human understandable scale: http://news.ycombinator.com/leaders
