Yeah, some of her articles don't add much to what I already know, but I bet other people say the same thing about articles I find really interesting, and where I like that she starts with basics.

Many (maybe "more interesting") articles about deep details of something don't get much attention because you need a lot of previous knowledge to understand what is going on, that hurdle almost never happens with her articles. Introductory articles often get more attention that way.

And sometimes I notice that apparently I didn't know as much as I thought about the details...
