I'm all for learning magic and I love Peter Mckinnon but I've been thinking about this. Isn't a post like this a type of exposure?
Peter performs a trick online and now if anyone searches his name they are lead to a thread about a bunch of guys sharing his methods. I know it's a big gray area, and that no one here wants to actually reveal his magic, but posts like this make me hesitate to put magic online because it might end up on a forum like this.
