Well it took some time, but Google has finally narrowed down the list. Last November, I blogged about Google’s Project 10 to the 100th – an innovative global participatory marketing effort established to celebrate its 10th anniversary. Touted as “a call for ideas to change the world by helping as many people as possible,” Google garnered over 154,000 entries, and is now ready to invite consumers to vote for their favorites – the ones that they think will help the most people the most. While the process took a little longer than expected, Google whittled down the entries to sixteen “big ideas’ and is ready to write a big check as its advisory board looks to choose up to five projects to fund based on the votes.

Google’s Project 10^100 demonstrates the power of participation and takes cause marketing to the next level with a huge prize that has inspired some great thinking that just might change the world.

So where do you think the money should go? Do you want to help provide quality education to African students, drive innovation in public transport, enhance science and engineering education, create a genocide monitoring and alert system, or promote health monitoring and data analysis? Well – it’s all up to you and let the voting begin.
