So far that's pretty obvious, but it's interesting to think about the second-order effects of this. It means that the current ad-based business models with open access no longer work. Instead, it's all about trust. People will be willing to pay for communities that guaranteed to be "human-only" and where content is created by trustworthy sources and trust is quantified and monetized somehow. This also includes verified credentials of posters, pseudonymous or not.
