If Steemit is serious in crossing over into the bloggersphere pageviews need to factor heavily in the payouts/ ecosystem. People like to know how popular their content is (not just engaged readers but also passive ones), they would also expect the rewards to be commensurate to the amount of eyeballs they bring to the platform.
Even bloggers who are not driven by the financial rewards like to know what content they put out is attracting an audience, so they know where to focus their efforts. I dare say the data is also valuable data to the platform developers themselves.
Could it be possible for people to volunteer some stats about themselves, but have those stats encrypted the blockchain? That way creators can get that information without it tying back to any particular user.
