If I read a chapter of a story, I always react to it, at least the author knows I've read it then and enjoyed it. I am trying to be better at leaving comments, and I do except when I'm reading on my phone (the screen is just too small to see what I'm posting properly).
Of course, I am always grateful for all the likes and comments I receive as an author, and I try to reply in a timely manner to all of them, even if it's just to say thank you.
@droughtquake Your comments are always welcomed and appreciated
