I enjoyed them - I think it shows how you can make a (relatively) rigorous, yet intuitive, argument that does not necessarily have all of the trappings/wall decoration of traditional proofs. The art is noticing when the story is complete vs. when it is papering over an important mathematical aspect.
I took the course in person, so it might have been more understandable in that context.
Me too - particularly when the story proof was more concise than the algebraic proof, or hinted at the deeper reason as to why something must be true. I remember them better too.
