Online giant Google is helping assist cyclone victims and survivors in Myanmar and will be matching up to 1 million dollars through UNICEF and Direct Relief International. Go to there support page to participate in their matching gifts program for relief.
On a side note, while a matching program for 1 million dollars is a great start, and I don't know what Google is doing otherwise - it would be nice to see them reach that goal and then push it up to something larger - maybe something like $25 million.
