so what if 3/4 of the people are crappy and decide its not there thing? its the 1/4 that counts you never know, the next David blaine could come from this site and i think its a great effort
I'm sorry but i don't think its worth it because you forgot the remaining 3/4 of the people who are probably doing the tricks from time to time whether its a card trick, coin trick or whatever poorly ... Learning a trick like Blind by D+M is very appealing to non-magicians, and if they bought blind before getting dissapointed by the deceptive method, you can surely expect them to buy something like lets say the "Be Kind Change" and probably won't be able to do it because they did not take the time to learn the basics and progress little by little from there, they just want to learn something right here, right now. Even after they learn a couple of effects, they are probably gonna perform it for friends or famillies AND if they are not into magic, i guarantee they are gonna REVEAL it, trying to be the cool one. That guy who will respond to the advertisment will be like any other guyz that all of you are very familiar with, its the one that says "How did u do that" after every trick, do you think they wanna be a magician ... Of Course not, they are just curious about the method. No one will look at an advertisment and say, "Oh i wanna be a magician". Try to remember what got U into magic, it probably took a lot more than that ....
When it comes to the next DB, i don't think its a good idea to throw a 100 bait into the water (the secrets), hoping to catch one big fish (D. Blaine), its just stupid.
