But the reality is it is no different than me using ocd or oc hoping for extra votes, other than by using reward.app you are giving up a part of your reward and redistributing it back to the people that voted for your post.
For a person that is on a good curation list, (yourself), it is not going to attract more professional curation trails. (ROI is based on getting there first to maximize return). So it is not buying.
It is a way for a future coder who wants to start a more valuable curation trail to make a few extra dollars. I can see the advertising now for the list: Come follow my trail, I vote only on the reward.app users. With every vote cast you will receive an extra minimum vote reward of 4% So Billy Joe Bob can make 4% or more on their votes on that trail than Mary Jo Sue can on the vote trail she follows.
Will it disincentive people to do their own voting, not likely, will it make the vote trail followers look for new trail for more curation rewards, possibly. Will reward.app get enough users to provide the incentive for new trails? That is yet to be determined.
Still a very new system, I guess we need to just keep watching and learning what direction it will take.
