This is one of those subjects, like religion, politics, and the ever amusing blaine vs. angel, where people r never going to agree. Some say its ruining magic, others dont, but i can tell u by posting what effects have tutorials ur not helping things any if u believe it is. personally i'm not worried about it because the videos r poorly done and they dont give u insight the way the pros do about the various nuances. Also its not the secret that makes the effect, its the performance and patter which gives it its power and thats something none of these youtube yuppies can show u how to do. We as performers make the effect, not the secret. And i have yet to have anyone call me out on any of my tricks so youtube is failing miserably at ruining MY art.
