I tested this and it worked, and now it doesn't, so here is my assumption of what happened: 1) I click it from Google, it sees that Google is the referrer and saves a short-lived cookie that says I'm allowed to see the whole article, just in case I refresh 2) I try the link from HN, it works because I still have the cookie 3) You click the link from HN, you don't have the cookie, it fails 4) I try again in the evening, I don't have the cookie anymore, if fails Anyway, click the "web" link near the title and click the first Google result.
