I don’t have any problem with self-help articles per-se, but I definitely have a problem with unoriginal content — and none of these articles told me anything I hadn’t heard twenty years ago. (I am twenty-eight, and I don’t think I was an especially well-read eight year old.)
Tell me something I’ve never heard before. I don’t care if it’s stupidly wrong. In fact, maybe it’s better if it’s wrong.
