I am good at code review, sure, but I don't like doing it. It's about as strong an engineering technique as coding at a whiteboard. I know I'm at a tiny fraction of my potential without debugging tools and for that reason code review on github is usually a waste of my time. I'll just write code thanks and I'll move the needle on quality by developing. As a reviewer I'll scan for smells but I assume that you too would be most effective if I left you make and clean up your own messes so long as they aren't egregious
