I would also suggest you have instrumentation set up for your app so that you can see how users are using it. I've used mixpanel.com before, it's free to start with. That way you can capture key user interactions that you're interested in (eg, are people using the "foo" button?). You can also use it to catch exceptions, especially where you think there might be issues like with your ssl cert.

Good luck, I admire your initiative to "ship" your project and it looks like you are getting good feedback on HN thus far.
