No way this would fly. A down vote would potentially server you off from so much discussion.

But I do strongly think something should be done to stigmatize or coax users against heavy use of down voting.

Users should not be able to suck karma from the system as effectively as adding karma to the system. I'm pretty convinced there's a handful of folks very dedicated to cancelling karma they don't like, and who spend lots of time & effort undoing the hope & joy others seek to spread.

That's gross. I'd like to see something to push towards the positive.

I was thinking about comments, that is someone that downvote one of your comments should, from that moment on, not be able to see any of your other comments. But the title of the post doesn't reflect my intention. I agree with you that those cancelling karma should no be able to expand here.
