Seems weird that if someone links to a news site, that the news site gets to double-dip advertising revenue, since it gets to advertise on its own site, and also get a cut of the advertising revenue of someone that linked to them. It will either mean everyone will want to classify themselves as news sites, or, people that link to them will no longer want to drive revenue via ads.
The issue is that most of the time the link doesnt get clicked on because the aggregators have summarized the content. facebook especially disincentivizes clicking the link.
Reminds me of this "Report: We Don’t Make Any Money If You Don’t Click The Fucking Link". The aggregators sucked a lot of the juice out from the properties themselves.
