ShocaDB was a service for keeping track of podcast and YouTube guests. You could look up a guest’s appearances across many shows, vote for who you wanted to see on a show next, and follow guests to get a notification whenever they turned up somewhere new.

It was one of our internal experiments, and a hands-on way to learn about structuring data from many different shows and sending timely notifications. The service has since been retired, but the lessons stayed with us.
