At the end of July, Michael Ellsberg posted something truly subversive on Facebook. It wasn’t a scantily clad photograph of himself. Instead, to his 25,000 or so followers he wrote: “Jena and I are no longer married. This has been a heart-wrenching process for both of us, over the past year, and we are thankful for the support of our friends, family and community in helping us through this. We are on very good terms.” (His former wife, Jena la Flamme, posted the same message on her wall.)
