SO SOME PEOPLE ON THE SITE ARE GETTING REDIRECTED TO AD PAGES WHEN THEY CLICK ON A LINK. Even when it’s a link to comments. It’s some sort of crap that has sneaked in via the ad network and the ad folks have been trying to block it but it’s insidious. Clearing your browser cache seems to make it go away. I’ve experienced it a couple of times myself. It is affecting some other sites, but it almost feels like some kind of attack. Anyway, sorry to those who have been affected, and we’re working on it. It’s by far the worst such thing I’ve ever experienced on this site.
