Even if the browser could read your mind and pay the perfect amount for content automatically I'm betting the model would have lower overall margins than the current model.
Why read my mind? Users deliberately kick likes and hearts and what not all the time. Also in most cases time show pretty good how much you valued some content.
The margin of the current model directly correlate with marines on the advertised products because obviously the users pay it this way indirectly. There is no way this 3 party model can be more efficient than a 2 party model.
Kinda but IMO it does it the wrong way. Using a special browser is certainly not mainstream compatible. And blocking ads can't be the solution. This is possible since years and it didn't change the system. Donations via flattr and the like are also nothing new and didn't change the system either. Its the walled garden problem again the internet will never accept one party as the right so everyone will use this and therefore every website only has to implement this. Flattr for example was a cool idea but since it can only be used on sites who implemented this it can not scale. There is absolutely no chance that the majority of all websites will use it. And if it would happen it would be very bad. A single company would have way way too much power then. We need an open standard that allows value transfer on protocol level. So everyone can agree on the same tech and different payment provider can share the market and compete against each other. The Interledger Protocol may be the solution to this. ILP is for value what IP is for data.
