Something like that, but it does not have to be hidden forever...

For example, I was thinking it could be hidden for a few weeks (customizable) and then automatically open up. This way, subscribers can have an argument for being subscribers because they want the absolute latest updates. But at the same time, who is following you, can still check what you do and maybe become a subscriber.

There are some things that make sense for this model.

The fact that it opens up, also discourages the "sharing for money attacks"... I would say, as no one will honestly pay for something they know its eventually get public.
