But it's still no good for people who want to charge, say, $0.25
A quarter is what the article hints at. I think that for a large newspaper site, some charges might need to be lower, and they would have to take into account users coming and going, bailing out in the middle of articles because they didn't like them, etc.
For many types of media, micropayments aren't like paying a movie admission and planning an evening around it. That might work for a movie online, but probably not for a magazine article.
