Sidenote: at the top is a "tl;dr" link to a summary of key points at the bottom. The link is a named anchor #toolongdidntread. When you click it, the page scrolls down to the bottom but the location doesn't change to the anchor. That means you can't hit "back" to get back to the top of the page.

It's just a small thing, but I find the cumulative weight of little touches that break basic browser functionality for marginal aesthetic reasons really start to grate on me.
