Long ago, I had the insight that not all users are equally technically proficient. Some had the chops to fix some problems if given sufficient information. Other users would be confused with too much detail.

I was writing code for AT&T (in the 1980s), and we were our own customer. So I wrote the error routines to check an environment variable and provide different error messages for different types of users: developers, testers, and a few power users got very detailed error messages, ordinary users got friendly, simplified messages (and weren't told about the environment variable).
