I’m pretty sure I found the "Page" font that is used on css-tricks in, for example, the "Chris is a web designer…" part of the footer. I found it on some website called "allfontz.com". I have no idea if it’s trustworthy or anything, but the font does seem to work on my mac.
Here is a link to the page I found it on: (you have to scroll down a bit, and on the website the font is called "Page Regular", but when you download it, it’s actually called "Page") http://www.allfontz.com/modules.php?name=allfontz&char=P&no=20
Here is the download link: http://www.allfontz.com/P/click.php?id=42
I have too much free time, i guess, but hey, I’m just a kid.
