What HowStuffWorks actually is

A long-running reference that takes one object or process at a time, whether a jet engine, a credit score or a nuclear reactor, and walks through it in ordered steps with diagrams. Articles assume no background and stop at the point where you could explain the thing to somebody else.

Why it is worth your time

It answers the specific question you had rather than the adjacent one an encyclopaedia would answer, and it never assumes you already know the jargon.
