Impressive stuff, although the book promotion page looks slightly off. Reminds me of those 'free make money' ebook pop-up's I got in 2005.
Just because one doesn't like it, doesn't mean it won't work. My learning was: Always, test everything.
This is a point that every single commenter on HN needs to be aware of. There are far too many people who seem to think that just because they don't like something, it can't work, won't work, should be priced lower...
"Test everything" includes "test the options you're dismissive of, just in case not everyone thinks like you."
Edit: You have my hard-earned now, after I saw the "which country are you in" - that was embarrassing, but in my defence its a terrible interface.
