One quick thing(but for the most part I agree with alot of what has been said):
Personally I think sharing of information is good and lends to the evolution of things, why impede something that will ultimately help the art that you are trying to covet?
I really disagree with this, at least until we are living in a communist society and creators can be supported without protecting their IP.
The fact of the matter is that in order for the art of magic to grow and become better, we need magical creators coming up with inventive, original stuff to push further.
These people need to eat and support families, and that means that either they have to work a full time job and try to find time to create magic, OR they need to be able to support themselves when working 40+ hours a week creating magic, working out bugs, publishing, ect and all that.
If we lived in a magical community void of ethics, respect for creators and lack of IP, then what would happen is as soon as anyone came up with anything new, it would get exposed to many and very few would buy the book/DVD/whatever(due to the lack of respect for the creator).
That person would quickly not make enough money to support himself as a magical creator and would need to find another source of income to live in today's society, and as such he wouldnt have much time for magic and the art would suffer.
Imagine this on a wide scale and you have basically how the community is trending now(currently many new people in magic will watch an online demo of an effect and then steal that effect for their show without buying the effect).
It has already forced creators to create less or come up with more secret ways to release material, either charging a lot to try to make only proffesionals(those with respect) able to afford it(in hopes it wont be stolen by the masses), or with non-disclosure agreements, or by only teaching the material face to face for a workshop fee...
Many on the whole has only suffered due to this trend, so I really cant agree that free information of people's recent creations is going to improve the art, at least not until everyone has enough generosity to send a hefty check to creators anytime they use the effect, because if not than the art will suffer.
Again, all my opinion but if you take a look at recent/current events in magic it backs this up.

ps I love penn and teller and have met and talked with both and they are great guys!(dont tell them I said that, tell them I said they were horrible for magic).
pps I also would like to point out that I typed a lengthy explanation that i know there are more than 2 types and I was simplyfying for the post(this part you left out of the quote). I would still say you fit more into type 2, whereby you just dont have the time or energy to pursue learning any effects, but by your nature of wanting to know the working and fanscinated with them you are the type to really appriciate the workings and in type 2.(but I agree that its oversimplyfying)
