Just over a month ago, my team at Google and I launched One Today, a new mobile app that encourages people to make charitable giving a part of their daily lives. The gist of the app is this: Every day, One Today serves you a new charitable project. If you think it's worthwhile, you can donate $1. If you're really excited, you can challenge the community to donate to the project by offering to match their donations. We're currently in a closed pilot, but one month out, I'm optimistic about the future of One Today.
