Study it, do not just read it

Before

Before you open it, spend two minutes sketching how you would build this yourself. Write down the biggest risk you can see.

While you read

  • Which number or limit forced their main decision?
  • What did they try first, and why did it stop working?
  • What did they choose not to build?

After

  • What would break first if traffic grew tenfold?
  • What did they trade away to get what they wanted?
  • Explain the design in three sentences, without looking.
