The best way to use ur SteemPower is to help others to grow in the community
Yeah ppl come here for the value of the place and I can tell it's way respectful and informative than fb
But part of it is that they gain something from spending time Sharing their experiences and life
So when someone write something really good and find no interest in his/her content , that disappoints them
So upvoting them is a good way to spend ur sp in my opinion
