Steemit obviously offers a powerful marketing platform. The daily increasing numbers of people joining steemit means that it offers a large (and by the way, still growing) and diverse market.
Personally howeevr, I would not be so quick to encourage ads. Why? Let me put it this way. Steemit is a media platform in which content creation and curation are both incentivized.
One of the challenges that confront the platform, is the fact that the quest for rewards, is taking away the necessary engagement among members, which, mark you, is a central aspect for the future of the platform.
What we should be doing, is looking for creative ways to’ encourage members to engage. Ads do the exact opposite. They distract members, often times leading them to other sites.
