For a while I had updated my CSS setup so that these sites would have a strike through on them and I'd go strait to the comments instead of trying to read the story.
The Information doesn't have a workaround, but they do unlock many articles for HN readers. I asked them to unlock this one and they did, so everyone who clicks on it from HN can read it now.
But it's easy to think of a random email of letters and numbers, and no further validation is required.
It'll convert well for them at least.
It's an attempt to create a high-value, investigative tech magazine. The paywall is rather strict and it seems to be aimed at the investor class, so I'm not entirely sure how well it's going because I'm not a subscriber, but I believe I've seen a few important stories that originated with them.
If it were the New York Times or some site I've heard of however, I'd happily login.
