This morning I was very pleased to see the success of the Mobile Campaign of the American Redcross. It's simple, texting "HAITI" to 90999 makes a $10 donation. $22 million according the to New York Times.
The gravity of the need, the compassion of people, and the simplicity of HOW you can help, made one of their most successful campaigns of all time.
Do mobile campaigns work? Yes. Compliments to the American Redcross for not only helping people, but for making it so easy for others to help them help people.
