The act of sharing also requires you to evaluate what you know . It is through the act of teaching that we can be more certain that we have truly learnt. I myself often think that I know something, but when I try to explain it to someone I often find nuances that I hadn't considered yet.

I don't think Leo is talking about giving the keynote adress at some GCC symposium but rather sharing with the intent of gathering feedback as to gain further insight into the subject.

It's not so much about training someone as it is about growing knowledge together.
