Great to see some more brainpower going into this problem. We at Rollbar (https://rollbar.com) have been at this as well for the past 3 years, and I'm still stunned from time to time at how useful exception monitoring is.
For anyone looking to implement something like Haystack, definitely give Rollbar a look -- you'll find most of these capabilities there (and much more). And if any of the Haystack or GitHub devs have had a chance to play around with both, I'd be really interested to hear any feedback; drop me a line (email in profile).
