Could you explain me how?

By posting content, you can earn some "sp power" and dollars. And with your sp power your upvote will have a value, which could actually have an impact on those authors your support. You can read the FAQ for more info.

I don't think I would have interesting enough content to post. And my aim here is not - as I already said - gain money. But I will try to be more "impactant" on you authors I follow... :/

Ok good for you! :)
