I am still a minnow here and do manually all the things like upvoting and replying. Because I think mere upvoting is not enough to engage with people, what is the use of upvoting without going through the post. But I am not at all against steemvoter, becuase there are many great people from different fields who do not have much time to do it manually so it is the best for them. They wanna reward the community in the best possible way.
