That's the most beautifully presented, worst idea I've ever seen.
edit: Sidenote: I've stumbled upon an interesting Google Easter egg: https://www.google.co.in/search?q=blink+tag
Edit: I just realized, it's a vertical carrousel, in its full glory with almost invisible next and prev buttons, and its 8x8 pixel navigation buttons. This summarizes pretty much everything that's wrong with modern web design.
No it does not. It's MUCH better experience. Maybe firefox has a crappy implementation of it? I've been using smooth scroll for as long as I can remember (except on linux where it was slow) and it is really that much better. Jumping randomly and trying to figure out where you were? Better than naturally move the view? Really?
That being said, I agree with you that this site is broken. I can't use pg-up/down or home/end, yet the site acts as if it were a regular vertical page.
