Can't stay logged in

Man, I love The Verge and would be on here commenting more, but every time I close the page I've been getting logged out. I'm not even talking about closing the browser or anything. I don't have this problem with the Gawker sites (Kotaku, io9, Gizmodo). I don't have cookies turned off or anything weird that I know of... I mainly browse through FireFox on my Windows 7 machine at home and Windows XP at work and I have the same issues at both locations. Any ideas?
