I came to understand it as users of the app willing to put a price on their visual attention, giving advertisers the ability to bid on users' attention based on the users' own tolerances, and then it all becoming an ad bidding network.

Except the marketers would pay you money (I guess, the coin) to show you the adds, and not say, a TV network.

I'd probably put a high price to my attention — $5 per second. If I get an ad maybe someone messed up, but I get paid dearly. A lot of people I imagine would be down to get paid some fraction of a cent per view, probably seeing more ads, but also probably making enough revenue for a handful of coffees every month.

Here the blockchain is the distribution network.
