From a media perspective, this idea has always interested me. Eventually, you put everything on the web, but you give paying customers first crack at it.
Of course, it works for huge stories like an exclusive look at Apple — which I paid $4.99 for just like everyone else. But it’s a much harder sell for most things.
Still, if you prove time and time again that you have great content, a small percentage (your biggest fans and maybe even your biggest haters) would pay to get it early.
