The whole Gawker Media suite of sites. That redesign is annoying, I hate how the sites adjusts to your viewport but the sidebar is scrollable, and something’s weird with the linking system, half the time I find a link to them it just throws me to the front page without even a 404 error.
Still waiting for Snopes to kill off that damned right-click disable script. Yeah, yeah, I can use NoScript, but if you view the site on several different machines and browsers yada yada yada.
