I like the site – and the white space!
The only observation I’d make is that the top navigation tabs don’t work as I’d expect. Regardless of what I click, the ‘Gambling’ tab stays highlighted, so it’s hard to see exactly which section I’m in.
Also, the point of tabs (I believe!) is to reproduce the idea of a file index. So you need to find some way to bring the active tab to the front and ‘connect’ the page to the tab. The way Amazon use colour coding is a good example, though personaly I find it a bit busy.
Nothing else jumps out at me as being ‘wrong’.
