I have learned something from you my good steemian friend. I know to be honest, never plagiarise, but you are so polite to mention people who have upvoted your previoues post. I take the time to visit each and every person who supports my post as I am doing here now. In so doing, I discover many good blogs and I return the favour they do for me.

BUt what about when my post is so well supported by more than 15 or 20 upvotes? In a busy day, it is not going to be possible to do as I am doing now. So you practice of listing the people and mentioning them is a good alternative, I think.
