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'.
