It's an interesting idea.

I guess it depends on the audience. For example, I run a literary magazine and something that has been noted in publishing forums is that when you charge a reading fee to consider a submission, it can cut down on the number of people shotgunning completely inapposite submissions to any magazine or journal with a free open call.

But that's a targeted audience, people who like contemporary literature.

If they're thinking "Twitter but you have to pay per post" ... I could unfortunately see a race to the bottom where most paid posts are ads or thinly-veiled ads.
