I think magic should be cloaked in secrecy. I am all for promoting magic, teaching whenever I can. But the difference is I'm teaching, I'm showing people who have a genuine interest. I'm not exposing just because I can or because somebody wants to know. The performances we are talking about on youtube and the masked magician hurt magic because of how it portrays magic. It makes magic look hokey and magicians look like geeks who don't have a life. Magic should have that Mystique about it otherwise you loose the whole flavour. When I perform my bizzare magic. People's interests are piqued when I bring out the shrouds and viles and brass pieces with strange ruins engraved on them. If they knew it was just a ratty old handkerchief and box I took outside and hit with a chain a few times much of the magic experience would be gone. I once saw a magician perform coins across. He took off his shoes, took out a straw mat, sat cross legged on the mat, removed two small wicker baskets, about the size of okito boxes and did an amazing coins across. His entire theme being how ancient magic is how special magicians are, how the secrets are passed down from one magician to another. He was taking his audience on a journey where few are permitted to travel, and it was mystifying. Yes he was amazing due to the presentation. But if he exposed the secret the entire experience would have been..well non magical. The fact is we are magicians. Otherwise go and be a story teller, play the piano, be a juggler where the secret is not so inherent in the presentation. Nothing wrong with any of these other art forms, I love them all and I love combining them for a well rounded show. In the end don't loose sight that magic is about magic. The problem of exposure is that you are cheating your audience out of a wonderful experience.
Penn and Teller do a great routine where Penn stands there and tells you how the effect is done while Teller performs. Is it entertaining? Yes. Is it magic? not really, incredibly impressive, but in a way a juggler is impressive.
My problem is more with bad performances. When a magician does really bad it makes magicians look bad. I don't know why, and its not true in every case. But it is that much harder to convince somebody to watch a magic effect after they have had a bad experience with a magician, then it is to get them to listen to a song after they have heard a really bad song.
Sorry for the long post. The truth is like many here I love magic, I even really like some magicians

Magic has opened doors for me that never would have been opened have introduced me to some wonderful people allowed me to travel and enjoy the lifestyle I am living. Do I take magic seriously, of course I'm a magician how else should I take it? Do I take myself too seriously? Nope I'm just a cog in the wheel of life and I'm enjoying the ride.
