Over the last week, technology has played an unprecedented role in bringing aid to and saving lives in Haiti. Over $22 million has been raised by the American Red Cross via text message (about a fifth of total Haiti-related giving to the organization so far). And then there's the role that Facebook and Twitter are playing.

Those social media tools, along with dozens of others, have been used to help family and friends locate one another, to direct food, clothing and medical support to specific locations, and to help direct rescue workers to individuals alive and trapped under rubble.

That's social media for social good, and that's exactly what NTEN and NetSquared want to highlight with Beth Kanter this spring at SXSWi.

Of course, we don't just want to talk about Haiti -- we want to highlight some amazing work from around the sector, while also building a nice little library of case studies we can all learn from. So, we invite you to share your social media for social good story. We'll choose three to highlight in our session, and we'll share all the stories we can on our sites and at We Are Media.
