Let's agree that serif fonts do not always carry boring stuff. And have a taste of it:
Programming languages should be designed not by piling feature on top of feature, but by removing the weaknesses and restrictions that make additional features appear necessary.
Otherwise said, Scheme wants to offer of a minimalist core of powerful primitives upon which one can build abstractions to solve (real world) problems.
Scheme universe is vast and prolific. As programming languages, Scheme dialects target various niches and implement various paradigms. Some of them are part of the standards (namely RnRS and SRFI).
The most famous paradigm and agreed upon practices evolve around Functional Programming.
Scheme might be a dynamic language, it can compete with its scions and sibblings when performance matters.
Few programming languages can compete with Scheme when it comes to Science whether it is Language Theory, Theory of Compilation or Artificial Intelligence.
That being said, Scheme implementations might be missing some love. That's a good opportunity for you to learn something useful and give something back. Or like others, make it your secret weapon.
