Social media is changing how people discover information and share updates with friends. Three trends are emerging: 1) status updates and messages are becoming the new way to find out about interesting places, products, and events from friends' recommendations; 2) how people share information is evolving from passive broadcasting to active engagement through comments and responses; 3) motivations for sharing are both to learn what friends are doing through their updates and to keep friends informed of one's own activities to maintain social connections.
