So, I answered this question:
not a great question really too basic for this site. In answering it, there wasn't much new or useful content generated - but it did end up being useful in my mind as an entry point for the uninitiated. I think there's value in that - but it's not necessarily expert level.
That said, there are situations where I think a "table of contents" is useful.
So, should I have done that or not?
