From a New York Times review by Clay Shirky headlined “Creation Story”:

Early in “Extremely Online,” Taylor Lorenz’s terrific history of the online creator economy (so far), she tells the story of Heather Armstrong, a pioneering “mommy blogger” known as Dooce, on a horseback ride sponsored by a clothing brand in 2013. Saddling up is famously hard on unhabituated groins, and the eventual pain had Armstrong recalling breathing exercises she’d seen in a book on natural childbirth. Later she blogged that one of her defining images of the trip had been “hairy vaginas.”
