Ask HN: What do you think about this startup

So i have to develop a demo for my friend who was accepted into StartupChile. The idea is you as a publisher pay people for tweeting your posts, articles and so on.

How do you do this?, well you buy a subscription package and then put a twitter like code on your site (yea i copied the twitter button :) ), the new twitter button, when clicked, lands you into a twitter like window and let's you send a "payed tweet" and you get like $0.15 or something like that.

Would anyone use it, do you think it would have success?
