The 2004 Indian Ocean tsunami showed, among other things, the power of the Internet to raise money. Now Haiti is showing the power of the mobile to raise donations for earthquake relief. Old-fashioned television telethons can stretch on for hours. But the latest charity appeal is short enough for Twitter: “Text HAITI to 90999 to donate $10 to @RedCross relief.” In the aftermath of the earthquake in Haiti, many Americans are reaching for their cellphones to make a donation via text message.
