ut books are harder to make and have an entire process. Johnny Chuckwagon won't release a book explaining ONE sleight because it's too time consuming. And NO publisher would get onboard a 6 page book...booklet...thing.
Publishing a book is sadly easy these days. In general I think a major problem with the magic world today is that there is not enough of a filter on how to publish material in any way. Anyone can put something on YouTube or Vimeo. Anyone can type up an eBook. Anyone can put a book on Lulu print on demand. There is literally nothing stopping anyone with the equipment from publishing anything.
The only filter or gateway is getting people to buy it. I could hammer out a 6 page booklet and have it ready to purchase on Lulu by midnight tonight. Could I get people to buy it? Survey says: Not really. I'd probably sell one or two to the folks who knows me well and are generally up for anything I'm willing to sell, assuming the price is right. Guideline: $.50 per page.
I realize that "unwelcome" isn't the right word. Perhaps, "closed off" or even "bored with answering basic questions" would be more accurate. It's very easy for someone who's on forums to get tired of answering the same question over and over. It starts out with bibliographies and footnotes and invites to contact them for help, and then turns into "Read this book, good luck!" And that's the helpful ones. Then, particularly in places like the Cafe, you get arguments over whether David Blaine is any good, whether the trick is any good, why anyone would bother performing that version when this version exists, so on, so forth.
The tendency for knowledgeable magicians to want to steer people to the "correct" sources right away can come off as a barrier. Sometimes it actually is a barrier. When someone just wants to learn a couple card tricks and they're told they have to study (study!) these resources and they'll be ready in two years, they're going to say, "Forget that, I just want to entertain my friends over a pint at the pub, I'll learn it on YouTube. Good enough." So for those people, I think having proper tutorials on the basics, on the old stuff, could be a valuable thing. Then they can be taught that you can do this causally and that's OK, and if you want to get more serious here are some resources.
