You have a good point, compared to Facebook, Steemit is indeed a baby in the market. Though I think that's all the more reason for Steemit to create a method of outreach like this.
Right now there's nothing that stops Facebook or other major social networks from implementing a similar solution, including creating their own cryptocurrency. Just by creating Steemit and making it successful, we put a target on our backs for larger companies to follow suit and copy. This is something that Facebook did/does very successfully.
In addition to attracting bloggers and readers to Steemit, we'll also be able to reach out to new people and get the name out there. I see this as an overall solid move.
