First of all, save the date, old building enthusiasts: The D.C. Preservation League’s 2010 Citywide Historic Preservation Conference is scheduled for September 24th and 25th at the American Institute of Architects’ New York Avenue HQ.

In the mean time, though, the National Trust for Historic Preservation has launched a new tool to keep historic homeowners talking 24/7/365: Maybe the world’s first social networking site for your house, trendily christened “@home” (not a Twitter handle, just the name of the site). Make a profile for your house, load pictures, chat with other preservationists in your area—it’s like This Old House in Web 2.0. So far, Pennsylvania is the most enthusiastic about the new service; D.C. is in 12th place with 16 profiles.
