Best wishes on the switch, but I'm afraid that the leap being taken is too big. Suddenly we go from bare HTML served by cgi to a single-page, style-rich and interaction-rich JavaScript application.

That said, I actually like the new website, except for the bottom bar. When i scroll quickly on iPad it doesn't always stay at the bottom, and it is especially ugly when there is one page being viewed. I'm sure there will be people with way stronger opinion on the radical UI change.
