would be great to see this in a pdf for easy reading

Here's a quick and dirty single page HTML version as a stopgap: http://danielchoi.com/software/thoughtbot-playbook.html

Awesome, thanks! how did you accomplish that btw?

Pipe it through Readability (http://rdd.me/) -> Print to File (option on left menu) -> Save As PDF. Works a charm.

Did you try? It's not displaying any more than 2 pages for me.
