If you keep an eye on vanity fair, the atlantic, new yorker, the sunday times and a few others, you're likely to read most of the good stuff.
Better revenue streams might increase the supply. You are right that a model similar to music is needed – I'm not going to pay 100$+/year for a magazine subscription, but I'd gladly pay 40$/month for 'the netflix of journalism'. I've also seen quite a lot of writers publish kindle shorts which could become 'the itunes of journalism'.
Actually, I think the free comments are what make HN great?
Mostly free, but if you subscribe you will get lots more (great) mostly long-form articles, and in cases where the article would normally be behind a paywall, they will do a special version for thebrowser's paying customers.
I find glancing through the medium.com homepage works pretty well if I'm just looking for one or two stories to read.
I'm starting to think we need a curation platform for long-form content. Preferably a subscription service that can solve the paywall problem elegantly. I don't use music subscription services because I want to keep the music, purchasing a file makes more sense. But I never save articles, I don't have the time to re-read them. Subscription seems perfect.
How much would I pay for such a service? Potentially a lot. If it could get me past any paywall or even just the most common ones I run into, I might pay a hundred bucks a month for it. I can consume a lot of long-form articles, many many more than I can books or movies. Subscribing to a magazine has too little signal-to-noise, I'm not looking for just any article to read. Nor do I have enough time to read a whole magazine.
