I always seem to strike it lucky with that site. I can remember it coming up twice on HN (once now, once a while ago - http://news.ycombinator.com/item?id=2290466 http://news.ycombinator.com/item?id=2290466), and both times I got a one-line equation. I didn't save the equation I got this time, but it was maybe five terms long and most of the atoms were zeros.
