Project Seed - oral tradition data

I really enjoyed Roopa's assignment of analog data collection. This is an idea inspired by Sarah's invocation in close of data that was only maintained orally.

Project goal is to try and collect data using only your memory and oral traditions. Without using hard documentation, how much data can you collect in a day?

Each time you interact with a person whose name you don't know, ask them their name. Make a tally on your hand. At the end of the day, try to collect how many names you were told. Are you confident about your collection? How "true" is this documentation? What did you learn, feel, observe, or change?
