IS IT RIGHT TO TEACH MAGIC ON YOUTUBE?

Just some thoughts on an issue that is hard for me to think through. Please comment.
Check this out: http://en.wikipedia.org/wiki/Exposure...)
See below:

I go through a few things in this video like:
Are there magic purists?
Teaching vs. Revealing.
Almost all card tricks are based on the basics.
Is copy right an issue when teaching?
I will try to improve my channel by not teaching tricks I haven't mastered, and not teaching tricks that are newly for sale.
Try to keep our comments educational by being kind and using logical arguments.

Thanks so much for watching.

P.S. Please keep in mind that I have never taught a trick that I learned on a DVD. I have never purchased a magic DVD or download. All of my tricks are ones that I learned by watching and imitating.
