WSJ.com - Google to Unveil Calendar Service In Further Move to Microsoft's Turf: "Google's Calendar, which has been expected by rivals and analysts, includes a number of features designed to make it easier for consumers to enter events and share them with friends. With a friend's permission, a user can simultaneously view the friend's appointments alongside his or her own. Consumers can also search and add calendar items posted by other users, such as the season schedules for their favorite baseball teams. They can invite friends to events and have the service keep track of the RSVPs."
