Thanks for the article, there should be a huge list of those type of classic C++ misconceptions/FAQ style.

One of my favorite is "you don't need a linked list".

Although I'm still genuinely interested when a linked list is best suited. I'm also curious why they were invented and why they're taught, maybe just for teaching purposes...

Maintaining an intrusive list of objects that you have around anyway is sometimes the simplest option, especially because objects can easily remove themselves from the list upon destruction.
