@Toni, Justin basically said:

Write self-explanatory code
Avoid bloated codebase
Document only the areas that need documentation, so even your future self will need reminding of what it actually does.
By listening to your users helps you write cleaner codebase, it pleases them as well for doing so, and you safe valuable time.
Keep the technical part(s) to those who really want to get their hands dirty with API and the likes.

In other words, a TLDR; of a pseudo-TLDR; is this: apply the UNIX philosophy - Do one thing and do it well!
