Thanks. This is an attempt at doing three things:
1. Learning more about the security risks of JavaScript
2. Facilitating a more create and nuanced discussion of its pros and cons
3. Learning about interacting with HN
I failed at my second goal and while I've succeeded in the third it was in different way than anticipated.
I also to reiterate that this isn't some backhanded attempt at a product launch. I would have hoped that my statements, using an appspot domain, no design and limited functionality would have made that clear.
