There isn't currently any "major content" to the site other than the links and the "Hidden Files" article right now, no. After all, this site is the part-time hobby of one person. I do want to add more content, and expand it some, but it tends to be on a "whenever I have time" basis.
As for the article itself, you may want to take the issue up with The Riddler (the author) directly. He's just registered on the forums, and I'll create a message thread just to discuss that article, where you can do Q&A with him directly.
