I agree. But that's not always the best solution.

Just like libraries, sometimes it is and sometimes it isn't the best approach.

For example, in a "How to do $BASIC_THING in python" article, putting an intro of "This is what a variable is" may not be a bad idea. Meanwhile, in a "Writing an operating system from scratch in an esolang I wrote" article, maybe you'd be better off linking to previous blog posts or other resources.

Obviously these are both extreme examples, but I think it's still a valid view.
