A week or so back they had one that I wanted to share, so I went to the website to see what the URL for it was so I could share it on.
And discovered that you can't do that - because the email subscribers get the stories a month ahead of the website. And, of course, the chances of me remembering after a month is near zero.
Why on earth would anyone do this? You're taking the people that care the most about SF short stories - the people that you want out there actively promoting your site, and making it extra hard for them to tell people about your product.
And as they don't actually send ads to the email subscribers, they don't get anything out of this barking state of affairs.
