First time I loaded the page, a giant scroll-locked ad took up more than half the page, and music started blaring. I go back again and no music. Scroll too far and you have a new URL, which if you refresh the page on, now you can't go back to the old article. I feel like this is all an artifact of web browser design. No stand-alone application would work like this.
