Yep, there is the competition against autos but in my opinion, it isn't necessary to mention in this case as if someone is paying attention, the autos are manually set by a human, they just don't have to watch every post. They can be gamed too. For a new recruit, they have so little HP that curation won't matter, but understanding the potential of it might encourage them to up their stake and participate in the community more. I personally think that in the beginning, it is either be part of the community for the betterment of the community to earn or, buy in. The end goal I believe is that the greatest mass of gainers will actually add and receive value, even though some individuals might earn more. Very few are good at curation, even with auto services.
