Yeah, I actually have the immediate response of bouncing back from that type of landing page. I have no idea what it does, so I have no incentive to sign up. I suspect that some may sign up just to find out what it is. I wonder what the effect would be of having that as well as some button or link to "Find out more"?

I think the results here speak more than any guesses we might make, but I'm just astounded with the results.

Side note: I was able to click "Sign In", and then from that page access the "About" page from the footer. That told me at least a little bit more about what the service is actually for.

Yup, the "Find out more" link is a great idea and something we're in the process of trying. We're doing an experiment with creating a 30 second video about the benefits of the site. We're planning to have a link on the landing page which says something like "Watch a quick video to find out more" which opens up the video for those users who are curious but not curious enough to sign up right away.
