The simplest way is to switch to writing shares based on visitors. By definition if you have readers you have been doing some promotion. Writers of fantasy and fan fiction can promote on those dedicated forums. Article writers can try to get their pages ranked on Google, to get search traffic, and so on.
I guess there's no hurry to change the share model because the advertising network hasn't been developed yet. But the issue of visitors will become an issue once it does.
I am planning on paying more for popular articles, however I don't have page view information to work with and I don't know when I'll have it.

Going based on hits/views is one of the easiest systems to manipulate (exploit). I am 100% against this.
I know fake page views can be made, but that would be blatant fraud. There have been several cases of undeserved earnings, but as far as I know, no intentional fraud. If there was fraud, hopefully we would detect it.
In the long term, I hope we could afford a bounty to develop a page level version of Alexa, which would be harder to manipulate.
