Using The Point to reach the "tipping point"

We are making use of "The Point" as a way to help us build momentum and reach our 100 people in 100 cities effort in 2011. The Point was apparently the offshoot of the people who brought us Groupon- online paid coupons that give 50% off (typically) for services once a certain number of people committed to the purchase.

It would be fabulous if we had more than 100 people in 100 cities. Indeed, there will be cities where more than one person or event will be held. But at the minimum, I am hoping we can reach the tipping point and have at least one event in 100 cities around the world.
