Jon and Justin talk about:
A stressful Rails 6 upgrade (and how it broke the app).
We often use data to make decisions, but we don't often examine the underlying data we're using to make decisions.
How do we know if our marketing efforts are effective?
"What's happened to your data since last quarter?"
"If a billion people are listening, but not reacting, does it matter?"
