I'm not so sure there is a bigger picture, just a bunch of people who each get different things out of reading/posting here on the site. Look at any of the comments on the articles about this so far, and you get the what and the why (people's reasons seem to run the gamut).

But let's postulate that we revert back to the previous system where comment points are displayed. I can't think of a reason why it would matter if I personally don't want to see comment points.
