Yeah... the fact that the only navigation links, aside from download, are below the fold completely destroys the usability of the site.
I don't really understand the value in the distinction you're trying to make.
IE a (typically) single page, completly above the fold, alternative to the official page of the site used as the page people see when they come via an ad or offer.
This is just a typical homepage for a computer language (listing accolades, testimonials, downloads, hello world, etc). It is much more featured filled than a landing page.
It just has poorer navigation than before.
