Please do not post / upvote paywalled content. I, for one, am sick of it. It has nothing to do with the actual article, but please - no more paywalls on HN.
I have been buying the Economist on paper every week for the last 20 years or so, love it, and I possibly also have the online version, though I never use it. But if the article is meant for public consumption, then let's link it. If it's meant to sell a subscription, please don't.
