JK,
In 20 years (I know it's difficult for you to think that far ahead), you'll look back on this and laugh. Don't try so hard to be someone who "teaches" around here. You've got some good qualities, but you can't expect to be more knowledgeable than many of the people here who have lived 2, 3, 4 times longer than you have. Relax, pick your spots, and try to be respectful of your elders ( ... which would be everybody ).
