I love the concept. I hope the execution will be right. e.g. if I pay for Economist story, I won't be bombarded with their popups.
We have a good privacy policy, here's the (loosely translated, this is not the official translation) first paragraph:
Blendle takes your privacy very seriously and will store and use your
information in a safe and secure way. Publishers have a tendency to demand that
we give them the email addresses of everyone who reads their articles, but we
refuse to give in to these requests. Also, we don't do ads, so we have no
incentive to collect data to sell you relevant ads.
