+1. Sounds more like an unusual job title than a revolution in the publishing world: "TPM Media LLC is hiring a Publisher who will be the primary manager of our audience growth, mobile media, business development and partnership strategies." (

Sounds more like a business development job, where the original owner is probably going to still pretty much run the show.
Plus, I'm not really seeing how this resolves the author's alleged "root of all evil," e.g. allowing editorial and finance to co-mingle. Seems like a totally separate issue, since TPM could have whatever structure it feels is appropriate or efficient in this matter, with or without a publisher.
