Others feel differently and are compelled to share just to get access since they like the concept enough. We did think about it quite a bit, which is why we removed the 'share to get bumped up in the queue based on your referrals' to 'just the act of telling your friends makes you important to us, and you're marked as a VIP in the db'.

Anyway, email+hn@domain.com gets you access today without having to share.
