Unsolicited letter sent during COVID-19 school closure in April, 2020:
“Just wanted to let you know that you have helped HUGELY with our homeschooling. Our kids are thankfully pretty self-directed, but having www.earthdate.org to point them to has been amazing. [Our son] is tearing through the episodes, and we are having some pretty interesting dinner and hike conversations. When [my husband] slipped on ice while we were out on Sunday, [our son] explained to us all why ice is slippery. He also warned us about avalanches, rattled off some rare  earth elements, and taught us a bit more about [Hurricane] Harvey 🙂. You have a big 9-year-old fan! Anyway, what a fantastic podcast series!"
