I might consider moving the "Try it on this page" button up to the top, or making the "try it on your site" feature not require a login until you're ready to save your tour.
A lot of webapps today have conditioned me to just click the big "try it!" button without reading anything else. So, I clicked the "try on your site" button right away, but then gave up when I had to create an account.
On returning to the site a little later then I discovered the option to take a meta-tour of the tour-generating product, but it certainly wasn't the first thing I could find on the page.
