I would love the option for pay for usage for many products I am forced into paying a subscription for.

I think one legitimate difficulty with micropayments for a news site (that has a few options to solve) is the reservation price of most readers for a single article might be lower than the cost of handling the transaction. The best option I can think of is the user needs to add credit their account or a credit card or something, which isn’t uncommon but I think some people might see it as a grift where they pay for more than they’re initially getting.

I think one benefit of it or shortcomings is it’ll probably kill off portions with smaller readership, but if that’s not you -you’re no longer paying for something you weren’t reading.
