There are hundreds of thousands of players playing in the poker rooms, what would helping the 4 or 5 hundred here that play 2NL and 5NL hurt a 100+NL player. And unless you have actually taught a sport or other activity ( I was a Karate instructor for 10 years and presently a personal trainer) it's hard to understand what teaching actually helps yourself with as far as following your own advice. If you study and teach, your learning as well. Most of these guys will have moved up long before we get to the level they are at now so they don't fear the students, they learn from them.
