The issue with paying for journalism is that quality journalism is spread out over many, many publishers on the web. I can't afford to pay for subscriptions to dozens of quality news sources. Until micro-payments or, more likely, a multi-publisher, subscription-based model is available, I would not be interested in moving to a payments based system.

Ironically, the most effective micro-payment or subscription-based system will probably come from Google or Facebook in the end.
