There's no way that affiliate links can pay the bills for publishers; numbers don't ad up (otherwise everyone would do it, and no one does -- well, actually, there's extremely limited situations where it works in some consumer corners, but those situations are limited and the total amount of revenue is also very limited). And how much extra traffic are you really going to refer? Ads are sold on the thousand -- $X per thousand (consumer can be cents up to maybe $8, B2B much higher). So even if you referred 200 people that's not even worth any effort. Unfortunately, if you're not going buy a subscription, register for a paper or click on an ad, you're probably not worth anything to the site anyhow.
