Admins do not, in fact, have the power to hide tensions on an article, as even the act of deletion produces public logs. Certainly if you don't know to look for them, you won't see them, though.

The main page should become a disjointed piece of both sides writing areas of the article. Right now, admins pick the side and moderate the other away into the history.

Good point. Would it be that hard to write a Chrome plugin that adds a "Tensionmeter" to each Wikipedia page?

Based on the edit and discussion history, the Tensionmeter could be green, yellow, or red.

The different parts of the article text could be colorcoded according to similar metrics.

I wonder what it would be for https://en.wikipedia.org/wiki/Toilet_paper_orientation
