Now try selecting some of the body text: only every second letter gets highlighted.

Take a look at the HTML source and you see this is deliberate: they are using JavaScript to overlay and interweave two streams of text with alternating missing letters into one block of contiguous text.

This oddball “DRM” might prevent casual readers from copying and pasting the text, but it also makes the content inaccessible to sight-impaired readers, and to search engines. The use of the monospace font also makes the text less legible.

Nifty!
