From the link:
"i'm is a new initiative from Windows Live(TM) Messenger. Every time you start a conversation using i'm, Microsoft shares a portion of the program's advertising revenue with some of the world's most effective organizations dedicated to social causes. We've set no cap on the amount we'll donate to each organization. The sky's the limit. There's no charge, so join now and put our money where your mouth is."
