I've been hearing that too Darren, and I have yet to test it, although I should (perhaps I should do a split test solo with you...could you do this? We could post results/case study here.)
Anyway, I once heard an old school motivational speaker....errm, perhaps it was Zig Ziglar, say that nothing sounds sweeter to a person than their own name. I've always understood that learning a person's name and using it throughout a conversation increases your influence...in person or over the phone anyway.
In terms of Internet Marketing...well, I'm in the business so there aren't too many tricks that get by me (in fact some of what I learned, I learned from Jerry up there years ago ~waves~...love your blog!).
Anyway, I typically ignore most of a webpage and email, skimming for the information I am looking for or to find the point of the page/email. In terms of personal preference, I might have to agree that less is more. Get to the point, or make it easy for me to get what I want, this includes purchases. I honestly do not watch videos longer than a minute, nor do I ever read long sales pages.
I think the digital marketing era that we are in now gives us about 8 seconds or less to capture someone's attention long enough to get them to take action...Keeping their attention is tougher, and getting them to come back after they've left your site or email is even tougher!
Perhaps collecting just the email would work in the short term, you can gather the rest of the info on a checkout form when they buy something, during a survey, or a contest. It's worth a try...
