Show HN: Track errors in your JS apps while engaging affected users

Hi! One of the creators here. We're creating an easy way for you to track and get notified of your JavaScript errors in your front-end heavy apps that use Backbone.js, Ember, etc. We also are developing a method to engage your users when an error happens so they don't feel lost (you'll see the model popup). I'm applying to YC with this concept and would love to know your thoughts!
