Aside, I like not showing the points on articles.
If you just polled new submissions and cataloged the number of upvotes over time, you could establish the best time to submit an article. If you want to get fancy, you could add some sort of categorization to the metric and break it down by category (like: "articles about node.js seem to get the most attention when submitted Tuesdays at 3:00pm")
I'm actually surprised at how much I like not showing points at all. I generally pride myself on carefully considering people's arguments and voting accordingly (if at all), but I've found myself reading comments much more carefully. It's too soon to tell what the effect will be in aggregate, but I my initial reaction is to hope the change is permanent.
