Officials at Causes, a Facebook application that promotes donations of time and money to nonprofit groups, says $2.5-million has been raised for 19,445 nonprofit groups, The Washington Post reports. The group says it has registered 12 million users who are now supporting more than 80,000 chartable causes across the globe.

Founded by Joe Green and Sean Parker, the goal of Causes is to apply the same viral-marketing principles that have worked well on other Internet endeavors to the idea of philanthropy and activism. Mr. Parker is a co-founder of Facebook and of Napster.
