Everyone does the early-bird special pricing for those who sign up for next year's conference by a deadline, but surely there are more creative ways to get people to commit to coming by putting their bucks down now. In reading Seth Godin's post, The magic of dynamic pricing, I was struck by how little dynamism there is in conference pricing. He's talking about e-books when he says this, but what a great ideas for conferences: "you could reward the market for getting excited. What if the price for everyone drops if enough people pre-order it?"
Anyone game to give it a try? Any other interesting pricing incentives people are using these days to get on-the-fencers to sign up?
