So you want to be a wizard
I get that these posts are intentionally written to make it look like a 12 year old wrote them, to give you the idea that it's not too challenging to understand. But it's a bit of a false premise: children can often pick up new concepts faster than adults. In addition, you're not going to express the idea better by putting in exclamation marks, hearts and stars, but you might turn off people who aren't 12. I'm sure Julia is a wonderful engineer, but I just find this writing style grating and I give up reading them. (I have the same reaction to lots of memes splitting up posts)That said, it's her blog, she should write them however she wants to.
