I wonder if there is an algorithm to score comments vs the article so that you can warp the article toward something the commentator would approve.

We have already seen examples where people run the same story on extreme left and extreme right web sites to get clicks and rage views and their toning, and changes are fairly algorithmic. That makes me wonder if you could build an echo chamber of one. So that what you read was always something you really agreed with, even if it wasn't written that way for anyone else. (same data and facts mind you, just slanting it toward the reader's preferences).
