A Mobile Link for 90 Mutual Friends

By ERIN KANDEL

Published: May 13, 2004

GONE are the nights when Brian Battjer left barhopping in New York to chance.

He took control of his social fate when he signed up for Dodgeball.com, a free social-networking service that is becoming popular with young singles. The site uses cellphone text-messaging to wirelessly connect thousands of friends, and friends of friends.

Just hours after he subscribed, Mr. Battjer, 27, received his first Dodgeball message: Alyssa, a friend of his friend Greg, it read, was at Luna Lounge, only two blocks away. Mr. Battjer had never met Alyssa, but inspired by the thumbnail-size picture sent with the message, he decided to find her. The two met and shared laughs over their mutually "dorky" fascination with technology, he said.

Mr. Battjer, chief operations officer of Watson Adventures, a company that organizes scavenger hunts, is now a regular Dodgeball user.

"Dodgeball has changed the social fabric of everything," he said. "The technology augments the social experience in a way that has never been done before."

Mr. Battjer is one of 5,000 people who have subscribed since the social-networking service was introduced on April 5 in New York and, two weeks later, in Boston, Philadelphia, San Francisco and Los Angeles.

"We think of it as technology facilitating serendipity," said Dodgeball's founder, Dennis Crowley, 27, who just received his master's degree from New York University's Interactive Telecommunications Program.

Based on the mutual-friends model popularized by Web sites like Friendster, Dodgeball helps users meet up with their friends or new acquaintances - but while they're out on the town instead of sitting in front of their computers.

"Friendster was a lot of fun, but does it actually do anything?" Mr. Crowley asked. "Dodgeball can change the course of an evening."

Dodgeball members subscribe through the site, then build a group of friends by linking up with current users or, as with other social-networking services, by inviting outside friends to join their networks. Members become "friends of friends" with the friends of Dodgeball users they invite to their network.

When members want others to know their whereabouts, they use their cellphone to send a text message (like "@ Luna Lounge'') to the Dodgeball e-mail address for their respective city, like nyc@dodgeball .com. The service matches the location in its database of geocoded bars and restaurants, and sends an automated text message with the user's name and location and a head shot to all of their Dodgeball friends, as well as any friends of friends who have checked in within a 10-block radius.

Dodgeball.com is popular among barhoppers. Many say the service is a good alternative to calling friends from noisy nightspots.

"It's like a shortcut," said Alexander Clemens, 36, a political consultant and Dodgeball user in San Francisco. "All it takes is one quick note to tell my friends where the party's at."

Others join Dodgeball to meet new people. Pictures sent with Dodgeball messages help users spot one another in a crowd, or act as an incentive for on-the-prowl singles to meet friends of a friend. Mr. Battjer says he feels comfortable meeting up with the 90 friends of friends on his Dodgeball network because each is directly connected to at least one of his 16 Dodgeball friends. At Friendster, friends of friends can be estranged by six degrees of separation, but Dodgeball allows only two degrees of separation.

Mr. Crowley (who says there is no particular meaning to the site's name) began an early incarnation of Dodgeball four years ago as a city guide based on user-contributed content. It didn't catch on, however, so he and his classmate Alex Rainert, 27, turned it into a social-networking service for their master's thesis project.

Clay Shirky, an adjunct professor of communications at N.Y.U., predicts that with a little time and fine tuning, software that "caters to users' geography rather than their affinities" will take off with the same force Friendster did two years ago.

"It has already been successful," Mr. Shirky said. "But eventually, Dennis and Alex are going to figure out uses and applications they hadn't even thought of before."
