To be fair, there is a monetary aspect behind streemian.com (of course). Those are for one, limits that you can exceed after paying a fee (I am working on this currently) as well as premium features for very low money.
There is another aspect of it that is someone controversial and that is: Since I have voting power over my customers account, I could use that to upvote my own content and thus profit from my user base. Currently, streemian.com does not do that and before I plan to do this, I will ask people to either opt-in or opt-out of this particular revenue model.
More to come in the months ahead. Anyways, streemian.com is mature every week and becomes more and more robust as we speak. I am confident I can go out of private beta sometime soon (tm)
