Reply to Some articles only view-able on the mobile site?

I've noticed that some of the articles on the DJTT main page i only see if i am viewing the site from my phone. Check these screen shots:

As you can see the 'Traktor Key Detection[...]' as well as 'Traktor Pro 2.6.1[...]" article do not appear on the main page of the sight when viewed on my desk top. I noticed this awhile ago with another article but thought it was just a fluke.

Anyone else notice this? Is it some setting on my main page? Am i just crazy?
