San Francisco has a new blog, sf.curbed.com, for those obsessed with the real estate industry. Founder Lockhart Steele (pictured) “has been tracking New York’s real estate market for almost two years, becoming essential reading for the city’s housing fetishists,” the Chronicle’s Rachel F. Elson writes. “Now the 32-year-old Steele is expanding his empire” to San Francisco, where local editor Phil Ferrato and contributing editor Alison Laichter are “covering dog battles in Bernal Heights, San Francisco fireplaces and the change in Japantown ownership.” Elson says the tone of the new blog is “sassy, salacious … In short, it’s real estate as pornography.” (Photo by Mike Kepka of the Chronicle.)
