What more info do you need? If it wasn't obvious, you are supposed to open your site in the Opera browser, making sure Javascript is turned on. You'll see how it just can't load.
Sitting in Europe (ping time 107 ms to your site), using Opera 11.01 on Windows XP I see the behavior joe_bleau described -- in the URL bar there's constant reloading visible when Javascript is turned on.
I just had the same problem (redirect loop), but not on your page, I hit it on the link next to yours on the front page: http://news.ycombinator.com/item?id=2350430. Maybe he confused the two?
