John, I don't believe that the TED model is a good or fair model for the MCW. I have spoken at IdeaCity, based on the TED model, and have agreed to the copyright common for my presentation to be posted on the TED website. (My presentation, by the way, was on the Riffle Cull.) TED presentations are basically focused on ideas, ideas and subjects that are presented in 18 minutes or less. Generally, much less. They are meant to be conversation starters, initially for the delegates who attend, and now theoretically, for a much wider audience. The people who attend the TED conference, which number in the 1000s, pay up to $3,750 for the privilege of attending, and the conference receives hundreds of thousands of dollars, if not more, in the way of corporate sponsorship. None of the speakers are paid, and they are not meant to be reimbursed even for their hotel or travel expenses. The primary purpose of TED is networking.
As for online viewing, people pay around $500 for live-streaming of the presentations. Only afterward, and sometimes much afterward, are a portion of the presentations made available to the general public online.
So, to have the Magic Collector Weekend Conference presented on the TED model, we would have to charge thousands of dollars for people to attend, not reimburse anyone for their hotel or transportation charges, pay absolutely nothing for talent, restrict the length of presentation to 18 minutes or less, and charge for the online streaming of the event, and then consider releasing a portion of the programming for the general populace.
I understand that your probably meant that, by the TED model, access was free to those on the internet, but my argument is that it is not free, that someone has to paid for it. Magicians have been spoiled by the quality of conferences and conventions, and the price point to attend them, particularly when compared to what other non-magic associations or forums charge for business-related conferences. I do not believe they will pay for much more. Also, I don't believe the bump you imagine in attendance or subscriptions will be sufficient.
If you are really interested in Erdnase, you will consider subscribing to Magicol to receive the Erdnase-related issue or acquire a copy on the secondary market. The magazine is bargain, as Clay Shelvin has suggested, because it is heavily subsidized like most magic magazines, by the many people donating time and talent to make each issue happen.
I'm not trying to single you out so please do not take offense. I have just heard so much about the "TED model" over the past few years and, having participated in it, wanted to bring some clarity to what it is - and isn't - at least from my experience.
