My mistake, the large subscription popup that appears on page load appeared to be a paywall to me. It does allow you to exit from it, though it had me a bit confused.
Thanks for the update, HN traffic is valuable to us and often generates interesting discussion, so I want to ensure that the paywal is disabled for it =).
The current browser I'm using is Firefox 23.0.1 on OS X. My UA string is Mozilla/5.0 (Macintosh; Intel Mac OS X 10.7; rv:23.0) Gecko/20100101 Firefox/23.0
Thanks for speaking up. That's one of the great things about HN - primary sources standing by!
