I was surfing twitter and AxiomZen webiste and somehow landed on your blog.
First of all, thank you for sharing your experience. It is very valuable lesson for any developer whose product is gaining traction. One curious question though [dev to dev], hasn’t this been avoided by use of Unit Tests and Integration Tests scenarios. I am keen follower of TDD and after reading the entire post, in my opinion as a developer, I think this is one of the learning as well.
PS: I do not know the background and entire story about Toby and it’s developement however, I installed it now and loving it.
