You might not be the target audience for this page. I think this is more about educating people who don't know what A/B testing is. (edit: if you are on HN, you probably don't need something this juvenile to explain the concept)

A lot of people will need something thats this simple to digest on their own speed, though. I will be sending this link out to a few past and potential future SMB clients.

The amount of people like "Bob" who are running their own website is astounding. They need simple things like this that help introduce them to the idea of A/B testing.
