===Jargon===
Users have also been defined as someone who pays to use a computer, or someone who asks mundane questions without thinking to read the documentation. They are distinguished from programmers and developers by just reporting bugs instead of being able to troubleshoot them in any way.
Users are looked down on by hackers to some extent because they don't understand the full ramifications of the system in all its glory. The term is relative: a skilled hacker may be a user with respect to some program that he or she himself does not hack. A hacker might be one who maintains LISP or one who uses LISP (but with the skill of a hacker). A LISP user is one who uses LISP, whether skillfully or not. Thus there is some overlap between the two terms; the subtle distinctions must be resolved by context.
