I’m missing tip 3, it is empty in the key tips.
Replying to other posts is what I do often. It generates more steem for me then my own posts. I do only comment when I think that I have a meaningfull reply. It is also which build a community. There is a change that the person to whom you post a reply, which could have more value in the end than the instant reward you get for the reply and often it is very much appreciated!
Keep on going!
