Hey, thanks for pointing that out, that's the second time I've heard that recently. I think Ghoetery is getting a little over-excited and hiding the parent element containing Disqus which also contains the body of the post. I'm going to take a look at how to rejig the markup so that this doesn't happen in future.
It's a stupid interaction with Disqus. I don't think it's the site's (troyhunt.com) fault because the text of the article is all in the original HTML of the page. It is Ghostery and the way it blocks Disqus that causes the article to vanish.
Err, we've got a bug in Ghostery 5.0 for Disqus specifically that will be fixed in 5.1. Its related to click-2-play, so you may either disable it in Ghostery advanced options, or unblcok disqus on the site.
I kept using ghostery because I didn't know of any alternative and sometimes I can't install adsuck. (which is is better than a huge hosts file. An oversized hosts file can have a negative impact on DNS and overall network responsiveness).
Try using Readability. Even if ghostery blocks the content after it loads, Readability will just format it and show it to you, without sending data to Disqus et al.
I know I know, I just shouldn't use Ghostery but I like to have a little privacy online.
Sorry I won't return to your site again...
