So essentially you allow the new guy to work on the marketing side of the site without fear of "breaking" any of any critical backend functionality? I assume he was able to get started fairly quickly (not much to learn besides some html and css).
I love the thought of A/B testing. But like you said, until I hit that 100/$1000 threshold, I still need to work on a lot of other things besides conversion rate (i.e. marketing.)
Looking forward to secret weapon #1.
