If I subscribe to the NYT for $5/month, then in order to "get my money's worth", I use NYT as my primary source for news. I visit newyorktimes.com every day and see what today's stories are.
After 30 days of that, I am an NYT user "by habit" and thus a loyal customer. I'm not clicking through news aggregators as much anymore, because NYT.com is obviously better I tell myself, or else why am I paying $5/month for it? NYT wants customer loyalty to their brand so they get that consistent income and sign long deals with their advertisers.
This sounds a lot like cable "unbundling", which consumers want (or say they want) but Comcast will offer it over its dead body.
Now maybe you can sell this to independent blogs. But TipJoy (YC 08) tried that and went bust, so it's an uphill road.
