Is it 1999 again?

Even if you can't see more than the 3 boxes on the page, you have a scroll bar and a large, softly pulsating link that says "Sign up now, it's free ↴". And if you don't scroll down, all of the navigation is right there at the top anyway.

I'm glad they ignored the fold, and I think all designers should aspire to this level of quality and attention to detail in their own work.
