Ah, yeah, that's the dealkiller for us -- we don't want our content duplicated online. Too bad, we were looking at it.
We are still developing the product and we have been thinking about making it optional.

The reason we are not implementing a signup when reading articles, is that it would make it impossible for your magazine to be shared. People want to share what they read and they often have friends who are interested in the same things. Those friends are all potential subscribers and it would be a big barrier for them if they had to subscribe in the app before they could read a single article.
If the subscription also allowed a user to view the articles online, I'd be fine with that.
