E-postage is a very old idea. It was a bad idea 30 years ago, and it's a bad idea now. I wrote this white paper 20 years ago, but nothing important has changed: https://www.taugh.com/epostage.pdf >Another example is with web pages having a charge to read, meaning that journalists can avoid having paywalls by having a >standard pay-per-article system that is managed by an account linked to the user's web browser.

The Web is in essence a version of Ted Nelson's Xanadu system, simplified enough to be possible to implement. Ted always wanted royalties per byte, but neither he nor anyone else ever had a plausible way it could work. Also, users hate hate hate metered services. That's why your mobile phone plan has a bundle of minutes (probably unlimited) rather than pay per minute, even though per minute would likely be cheaper for many people. R's, John
