What if they already are? I can think of a handful of newsletters that command a three-figure annual subscription price. The people who buy them must regard them as useful and of sufficient quality. It could be that the rabble of news sites drowning in ads are mostly schlock, and that their business model is one of attempting to monetize some of your least-attentive moments.
I'd like a system under which creators of quality content would be equitably and fairly compensated. The present system fails this.
