Users on Tsu also upvoted others' posts and each were rewarded. One big difference was, it was by invitation only and if someone joined with your invitation, you received a percentage of what they earned on the platform. This led many to spam Facebook with their invite links and in return, Facebook banned the links. One problem is they relied on advertising.

It had 3.5 million registered users in its first 6 months. Membership declined swiftly when earnings did not live up to most users' expectations.

That reminded me of the user you used as an example in your video. I'm not saying the same will happen with Steemit, just that it's something to consider.
