I'm a rational person. Do the studies and let's get the numbers. Appealing to jealousy is all I can see from people saying that participants will leave in droves and it doesn't seem to be based on anything we know from psychology. According to psychology, intermittent reinforcement with variable ratio schedule is the most sticky of all. Facebook users can't leave in droves and don't abandon the platform because they don't get enough likes. They do leave when they find another platform which is more sticky but from the data I saw, Steemit is already nearly as sticky as Reddit.
Anyway, we need more data driven decisions rather than to just assume.
