The New York Times looks at LifeAt.com, a social networking site that creates password-protected Web sites for apartment buildings and housing developments.
The company, based in Brooklyn, is surviving on the roughly $6,000 it receives from each building that signs up for the service. It does not charge the buildings yearly fees.
More than 335 buildings have joined since LifeAt began in March. About 600 more buildings are scheduled to introduce LifeAt Web sites by year’s end. The company does not currently share ad revenues with the buildings, but Mr. Goldstein said that could change.
Among buildings with LifeAt Web sites, Mr. Goldstein said, residents of 64 percent of the units have created personal pages. Property managers, who give residents login and password information, also use the sites to post news about maintenance work and vacancies.
