The everyday viewer will be rewarded for their efforts through the curration rewards. The Steemit curration reward is designed to help ensure that blogs are written with quality in mind. In the end the success of Steemit will depend on an audience developing, one that will come back to the site time and time again. And that will only happen if the content is attractive.

It is true that after only six months of operation there are many attempts to game the system. Largely through the use of robots, and the assignment of voting to others. I also see frequently cheating in cut and paste plagiarized blog content. Hopefully, the community will develop methods of defense against these attacks on the basic principles of honesty. A community can only develop in an environment of trust.

The Steemit White Paper foresaw many of these attacks developing, given the development of similar attacks on other social networks. Given that Steemit is only months old it has done very well so far.

Whether Steemit will need to accept advertising is yet to be seen. But it is my understanding that external funds will be fed back into the system to help maintain the value of the Steemit Dollar on the exchanges.

Steemit as a solid foundation. It is up to the user base to ensure it grows through voting on quality content, and thus encourage those who post to provide their audience with ever growing quality.
