Cal's "three questions" for Shaun about his website BreweryDb.com and its API:

• Can you explain what a open data/closed source model model is and why you chose it for BreweryDb?
• How do users know that BreweryDb won't change their data usage agreement on the API (and what problems it could cause on a wider scale, outside of BreweryDb)?
• What is the most interesting thing you learned while building an open API?
