This morning’s SunTimes.com has a good article on LifeAt.com a new social networking site for high-rise dwellers. The site provides social networking within a building. Four Chicago high rises, 340 on the Park, 565 Quincy, Prairie District Lofts and 600 Lake Shore Drive are on LifeAt.com. Superior 110 will be added soon. Each building’s site doesn’t provide much information for prospective buyers since access is restricted to residents. However, if I were looking to buy a home in a high rise, a social networking site just for the building would definitely be a nice feature!
