And what is more, am I supposed to subscribe to all sites where I occasionally find valuable content?

One of the good things about internet journalism is that I can read different publications very easily, every day. Some of them I'd actually like to pay, but not by way of a subscription, because paying for five or ten subscriptions at ~$30 per month each is just too much.

With paper newspapers, I can at least buy a single issue. With online articles, it would be feasible to pay per article, heck, even per half articles or whatever. But for some reason all the publishers come up with is obnoxious paywalls, and the option to subscribe or get lost. I honestly don't understand why micropayments haven't become a thing for online journalism.
