Odyssey, an online newspaper startup, raises $25 million on a network of unpaid writers

10,000 writers aged 18–28 each write one article a week and aren’t paid for it. They’re edited by professional copy editors, each of whom is editing an average 140 articles per week so they can’t be doing a thorough job.

Writers have to apply to write. For free. The benefit? They “swap their work for being edited and professionally branded.”
