I can't imagine how that could ever have worked. Back in the day, I mostly read stuff linked by news.google.com or in various mail lists. Now it's mainly from HN. But either way, I'd need perhaps 20-40 subscriptions. Which would be unworkable.
We really need a system that pays realistic prices (maybe $0.10 or so) per article read. Whatever you'd get by dividing cost per "issue" by number of articles available to read.
