It's one of those new, cancerous sites, where nothing is visible unless javascript has been enabled.
Because you need to enable javascript from two different sites in order to read a paragraph of text that could have been formatted using the HTML from back in the Mosaic days.
The firewall at the company where I'm currently at appears to be blocking http://strapdownjs.com/v/0.1/strapdown.js but not the github.io domain. They have strapdownjs classified as a spam domain.
