This is an interesting observation. I seem to fall into the former category, but I'm not sure if that's a side effect of working with proprietary codebases that have less than stellar interfaces.

When stuff ultimately goes sideways, I value being able to relatively quickly reason about the flow without firing up a debugger. Information hiding cuts both ways.
