I think it could be much better. You have to manually zoom into the article area on every page, and every time I scroll down it tends to scroll side to one side a bit since there is space to either side of the article. (I know mobile browsers tend to stop any horizontal scroll if it senses you are scrolling vertically, but not every swipe is perfect enough for it to do this.) Considering the desktop version and mobile version are identical, I suspect there was no effort to make it mobile friendly.
