Teaching isn't a simple matter you can flatten down to like/dislike.

One aspect of teaching is explaining your inventions to your peers.

But another aspect is telling a new graduate what a version control system is and why you need one. Then doing the same for your build system, continuous integration system, staging environment, code review, bug tracker, style guide, and so on.

Seems to me those are quite different skills - I can easily imagine a person who is good at / enjoys one might not be good at / enjoy the other.
