I'm not going to fork over $10/month to each of the other potential news sites for every article they publish. I have no idea why the Podunk Press and the Suburban Picayune Times even consider that as an option for out-of-area readers.
It'd be interesting to have a federated subscription model -- I'd pay an additional $X/month for all of the rest of the newspapers, and they could share that. They'll get nothing from me otherwise. Probably there is a business here (the tech to actually do it seems pretty straightforward, at first glance).
