Although we would have liked to receive an specific start date for Project 10100, Marissa Mayer, VP of Search Products & User Experience at Google, has announced that Google will be making some announcements regarding Project 10100 this fall. In an interview with Digg yesterday, Mayer said "We'll be making some announcements coming up this fall to close the process, get the public vote going, and ultimately decide on the winning idea or ideas."
Immediately before that, she offered two explanations for the delay: Google had to sort through the "huge response" and Google has to judge the feasibility of the ideas "to make sure that they can actually happen." Before now, I hadn't considered that Google has to gauge the possibility of all 100 ideas before they announce the finalists.
For example, one high-profile idea called ColaLife plans to use Coca-Cola's massive distribution network to distribute live-saving medicine to poor children. Before placing this idea on the finalist list, Google must contact Coca-Cola to see if they will cooperate, estimate the cost of implementing the idea, and gauge the probable effect of the idea. That's a significant task for even one idea, much less 150,000.
However, I'm not ready call this project a success. "This fall" is not an acceptable time frame; Google should announce a specific date. If they misgauge the date, they can delay it again, but until they commit to a date, they have no incentive to prioritize the project. By announcing a deadline, Google will become accountable to the public for any further delays. After 135 days of indefinite delay, Project 10100 badly needs accountability.
