Thoughtful comments is to me the fastest way to connect with others on Steemit. You also get to learn by reading through their work which often contains valuable information in the area of interest. To be effective with commenting. Choose to comments on issues that is in your niche. Make comments that contribute to the post either by supporting the author's view or perhaps constructive criticism. If you don't understand what is being discussed simply read and work away. I do follow your post @hopehuggs but on days you write on issues I know I can't contribute I just read and go back.
