You sure you don't just have a CSS modifier on or an incredibly restrictive ad blocker?
I only use ClickToFlash as plugin.
Strangely I could view the full article and the front page normally on my iMac at home, but with my MBP at work I have this problem. Maybe it is a server/router side issue.
I just thought it would be an effect of the downtime of the forum yesterday.
It isn't really important anyway, I can still read the articles from work if I click on the comments link.
I'm having exactly the same problem. For example this worked exactly once in FF4 (reloading broke it), zero times in Chrome, Safari, NetNewsWire, Camino. I do have ClickToFlash installed, but it (naturally) doesn't work with FF, Camino and Chrome.
Reseting each browser helped, but only once - after reloading the page it again appeared semi-blank.
