Because of the nature of things, people can be rude, this is life. Whether it's on purpose or otherwise, people get offended, and this can be counter productive. If someone answers a question with valid points, but phrases it in a way that provokes an emotional response, this can lead away from the real discussion, and in some extreme cases, ankle biting. My response is usually to kill it with kindness, but others may not react with civility.
In "real life", people's reputation consists of their intelligence, as well as their people skills. On SO, it seems that people are graded on intelligence only. Is this a good thing..?
It would be interesting to see how well liked a user is? If they found themselves down voted more than others, perhaps this would persuade them to change their attitude toward new users.
Anyway, this might be a terrible idea. Let the flaming commence! ;)
If you down vote, I don't mind at all, but please explain why - I promise that I won't take it personally; it's CW anyway ;) -- I'm actually fully prepared for down votes in this case, since now I'm wondering why "people votes" are such a bad idea (the general consensus is that they are, a very bad idea).
