It's interesting to see how no one even seems to try. In Europe there's Blendle [1], but that's only an aggregator and you still have to pay for each article you read (with hilarious differences in pricing).
I've always wondered if they'd be more successful with a flat fee for complete access to all articles for all their papers and zines. But I guess the publishing houses don't consider this viable as it would hurt their subscriptions (who's gonna subscribe to just one paper when there's access to ten more for roughly the same price?).
