Having a suggested $3/month subscription for having the PDF mailed to you but ALSO having the PDF available for free on the website could be the best of both worlds. Those who can afford to pay, do so, but you can still link to the free version (which could have nag pages inserted).
We will create a 'Content' section in magazine issue page on the website, where we list and link to all the articles appearing in that particular issue, along with its HN discussion.
Hopefully this provide an alternative for other readers.
