The long sales letter is the Internet beachhead of the pitch man. Maybe these kinds of sales letters work for some products. But Jeremy knows that he's signaling on Billy Mays (he says so himself), and that people who wouldn't ever buy from an infomercial wouldn't buy from a page like this. I cannot fathom the unhappy circumstances that would have me check "YES! I'd love to work with a copywriter who can make my life EASY and profitable instead of stressful and broke!" box.
The copy he writes wouldn't work on you but that's the #1 rule of marketing: don't project yourself on target customer. If you don't like long copy, it doesn't mean your customers won't like it. That's why stress is on A/B testing.
