Short Mention in The New York Times
From the article "Why Blog? Reason No. 92: Book Deal"
But there are successes. On the nonhumor front, the best seller “Julie and Julia,” about a woman who cooked one Julia Child recipe a day, started as a blog, and “The Hipster Handbook,” spawned from freewilliamsburg.com in 2003, has sold 39,000, according to Nielsen BookScan.The article is largely about the hilarious blog Stuff White People Like. Ironically, I mentioned this blog to my agent early in February knowing it would translate well to print. Looks like another agent beat him to it.
Incidentally, The Hipster Handbook has sold many more copies than reported by BookScan which often doesn't account for sales at independent and college book stores, the places where the satirical book has sold very well.
