I suspect it’s already been said, but a transcript or more detailed summary of some kind would be an excellent addition to the podcasts here.
This was the first episode that I encountered and I found the subject matter immediately engaging, but don’t find myself with lots of time for podcasts.
In any event, keep up the good work!

I always listen to your podcast when I travel, I liked how this one started. CRUD design methodlogy as a forms over data is a design issue. I think designing for intent is right, but I believe a most of this can be covered by a rule system. Collecting events in a DB so you can datamine if objects were removed from that cart sounds like “dumb” information to collect. Rules could tell you that someone intended to empty the cart because they were outside there budget, it add something by mistake.

@Steve
What happens when your rules change over time and you want to see how the new rules would have affected your previously observed data? The problem you will run into is that you are losing information by just having the rules. Keeping the events allows things to be repeatable.
