I will continue to collect commentary and images at sandradodd.com/learnnothingday. If any of your friends or relatives express doubt that people will learn naturally, or if they ask you if you ever take a break from unschooling, that might be a good place to send them.

Eleven judges, finally, pinpointed the four winning images. I would've gone with fewer judges, but there kept being ties. I wanted more than one vote's difference, so I recruited more judges. Thank you entrants and judges and viewers!
For writing on lists and for blog posts and links and photos of get-togethers and of cars with windows painted, thank you! I've tried to link back to everyone. If I've missed any, please let me know. You've helped me create an electronic monument to learning.
