That model sounds great. Low friction and impulse-buy pricing.

There are lots of sites (AnandTech being a prime example) I don't visit often enough to justify the usual monthly subscription cost.

Per-article pricing with no registration would be ideal (yet another cryptocurrency use case that never materialized) but as you say, transaction fees make that a non starter.

I have the next issue of always deleting cookies when the browser closes, meaning I'd get this dialog every time I visited the site. Whitelisting a site in Firefox is relatively annoying and throw in multiple devices, that dialog will always be there.

I don't really have a better idea besides automated micropayments, which nobody has managed yet, crypto doesn't count,, so I guess we'll have to live with the current situation?
