No, its not just SpikedHumor. Nothing that uses Quicktime is working... Not even just videos... The big...things on IGN's frontpages all are showing the Q symbol...
Should IGN be showing those? I remember when Flash was being told to open in Quicktime instead of Flash Player and for all flash animations the broken Quicktime would arrise.
Doesn't SpikedHumor use Flash to display their videos?
