And like everyone else says, the articles are skinnied down to newspaper width so you have to scroll and scroll and scroll and etc. And the comment organization is way better in the old system.
If you want the stuff to be all cutesy on a mobile, then just have a button near the top that says "mobile format." Sheesh. You'd think that wouldn't be something that needs saying on a geek-run site. (Or is it these days? Has Marketing taken over?)
So, yeah, like everybody else, one more vote for "Hate the new design."
