What do you think about this site idea.

I'm interested in education and specifically, how a website can make young people more EXCITED about learning.<p>What do you think about a "casual" or less formal instagram type experience where the goal is to share what you learned for the day, through text and images.<p>Kinda like the way it's done in this book. http://sprott.physics.wisc.edu/pickover/math-book.html Each entry = Images + Text
