Interesting idea: sign up for a regular monthly payment that gets divided among content creators you “heart” during each month. This has the right idea of no surprises (you know what you are paying however many people you want to reward); I wonder how the scale works: if you select 100 people does it ask for more money or just give them pence each?
Somebody after Kuhn said it takes about a generation for a full paradigm shift. I think we are roughly in the middle of the shift for copyright: the GPL is approaching 20, Napster started about 15 years ago, etc. Another 20 years and people will scratch their heads and wonder why voters ever allowed people to charge for content the way they once did. Bring it on.
