I pay for Medium and that's all right now. I would much like to see the micropayment future - it has to be part of the browser.
I would like to pay in lieu of time. If I could see page statistics of how much time it took for a page to be put together and costs of hosting - I could make a contribution based on this information. I've given random £100 to artists I love for the same reason.
From a sysadmin POV, the main benefit of the free-as-in-beer-ness of Free Software is that I don't have to deal with the bullshit of licensing, CALs, talking to sales reps and so on, even when my employer would have the cash to pay for it.
Likewise, the main benefit of free content is that I don't have to worry about things like monitoring my bank statements. I can and do pay for some services, and I could afford to pay for more, but each addition increases my financial cognitive load non linearly.
The thing holding it back is some kind of central authority that can process micropayments with significantly less friction and overheads.
Even better if people can accrue credit in some way that isn’t just paying fiat currency in, because we live as a privileged class to have disposable income that is essentially in escrow.
There are a lot of downsides to ads, but it is the most successful micro payment mechanism we have. It is also the most successful online business model we have.
Be careful what you wish for, I guess.
Attention as a replacement for hard cash. Hmm... So, how to control its spending as a consumer - that's the question. We're like natives selling land for glass beads. Can we omit ranting and make that a technological problem somehow?
