The Google IPO Swami writes: "I'm running an experiment and Slashdot readers would be good contributors. As you may know, Google recently announced that they will be using a unique dutch auction structure to price shares of their IPO. Instead of having the underwriters determine the opening price, the price will be set by the demand of investors that register to participate. I'm interested in how well the public can estimate this demand and the price of the shares to be offered. I'm giving away free shares in Google to find out. The person that comes closest to estimating the opening and closing price of the stock on the IPO date will win shares in the company."
