Suggestion about Karma

More and more the up-vote seems to say: "I agree" instead of "This comment has some value". It's not rare to see a comment like "This is great." to have more points than a "I don't like this because x,y,z" for instance.

My suggestion is just to separate those two meanings. We could have a very little graph like this:

  [xxOOOOOOO] # where x = red and O = green 

This would fix the "I agree vs I don't agree".

So, to summarize, it'd be possible on a comment to up-vote it (like we do presently) if it has value but still indicate that we don't agree with the author's opinion by clicking on another button.

I think it'd be really interesting to see the opinion of other HN-users in addition of the most valuated post.

And, as a bonus, we could see the total number of vote. Because, presently, some people up-vote, some people down-vote.. so at the end, the comment might have a score of 1. And, we can't differentiate between the +10/-9 (for instance) and the simple +1.

With the new solution, we could really see:

  - 10 agreed.
  - 9 didn't aggreed.
  - 23 think the comments has value.
