You've probably missed it, it's at the top, just under the image. There are 2 links: "Home" and "Back to freesound.org". You need the second one.

Huh, I’m pretty sure that wasn’t there when I read the article. I recall seeing only the “Home” link (and I did a Ctrl+F on the HTML and didn’t see any links that went outside the blog sub domain except for on a user comment at the bottom of the page).

But glad to know there is in fact a link now!
