Hacking Digital Calipers
While the article is interesting, it's a site that's annoying.<p>I use the keyboard to navigate articles frequently. This site intercepts keyboard commands - page up/down does nothing, arrow keys select specific elements rather than letting me scroll down.  Worse, the article does not load at all if you turn javascript off.  I spent a few minutes trying to figure out where the actual content loads from (since the page itself doesn't contain it and just references JS) - but gave up.<p>I can't see why they've made these choices, it doesn't seem to give any better UX than just having HTML and some CSS would.
