Left brain v Right brain is mostly bunk [1]. Additionally, the zine trend is nothing new. It is just making its way to computing in a way I have not noticed before. It's been common in music scenes, especially punk, for a long time.

I like it because it presents information in a more conversational way and has more personality. I like Julia's stuff because it feels like you're learning the topic with her rather than being talked at. Having hand drawn visuals also lets a lot of information be communicated quickly in a way that's harder than just text in some instances.
