Huh? That's a strangely hostile thing to say. Surely if I repeatedly experience my posts getting gradually upvoted only to then having them all suddenly downvoted so i go from +40 to -60 karma and all my positive posts are now negative... Then that's exactly what the OP is about? The only signal I get from that is that a couple people really dislike me/ my style of writing, and I don't think it makes sense to change entirely or go away purely because of that. That does not mean that I ignore what information each individual post's karma provides, however.
