> everybody only uses 20% of a given program's features, but the problem is that everyone is using a different 20%

This is a phrase that gets repeated and it sounds clever. But it's completely at odds with statistics, specifically the normal distribution.

We should say, people use 80-90% the same features, and then there's a tail of less common features that only some people use but are very important to them.

This is why plugin systems for apps are so important. You can build an app that supports the 80% with a tightly designed set of core features, and if someone needs to go outside of those they can use/build a plugin.
