> Experiment if you want, but as a guy, I would "nope" right out of there.As would I. I found the PyCon2015 talk by Ola and Ola rather too cutesy, but I liked the djangogirls' tutorial online just fine. I can imagine there are others who find the online tutorial too dry, and would like some of the cutesy stuff to maintain attention or interest. All we can conclude is that these techniques are not for the likes of you and me.

These are all didactic methods. Not everyone learns something best in the same way. As far as I'm concerned, there are still some people whose learning needs are not met by current mainstream methods. Any variation that attracts more people into the field ought to have a net positive outcome.
Consider this too: books for young children have lots of pictures in them, whether they're storybooks or textbooks. I can clearly recall a time when I was 6, and the first thing I'd do with a new science textbook is look at all the pictures. Back then, I found the books for older children rather dull. I grew out of that phase, as did millions of other children. Who is to say that these cutesy addons don't perform an analogous role in the early stages of some programming newbies?
