That’s a neat idea. Could be a YC startup idea. A subscription service that gives you access to all the paywall content let’s say 10/month for 50 articles and you don’t even click a button just read. Rather than seperate paywalls, ads etc.
From what I remember, they're a closed platform. One must use their apps to get access to full article content. That's a nice solution for their partners, but not for the broader web (85%+ of the websites you stumble across that are not TIME, NYT, Economist, etc).
Blendle is a nice experiment, but I wouldn't consider it a solution to the problem being discussed here.
