Haha! I like this. It's true though. We have the tendency to conform to the herd mentality. People only seem to seek out what is trending or popular at the moment rather than diversify and try new things. It is hard to think Facebook will continually remain on top with the current shift and decentralization of technology especially considering the tangent they are still on and the market they are targetting. However, if blockchain technology becomes widely saturated and implemented on a global scale, and like you said, if there is ever a Facebook coin or Token that rewards users on its platform just like steemit, then maybe they will maintain a dominant position in the social media league. But it will be interesting to see what happens in the future.
Facebook may just as well buy out or even merge with Steemit. Who knows right?
